Does the Identity Property of Multiplication work for Division?
NO it si like addition and subtraction IT DOESN'T WORK. Since Multiplication is somehow Addition made easier (4x2=8 ; 4+4=8), it can't be because Division is more of Subtraction and somehow to simplify answers at some cases. 1 x a = aa / 1 = a
Why addition and multiplication are easier than subtraction and division in computer?
Well, actually, division is just multiplication in reverse. Take 21 divided by 3 for example, and 7 times 3 is 21, so 7 is the answer for division. Try some new numbers and you'll get it! I've mastered division, so will you.
Which Chinese accomplishment made addition subtraction multication and division faster and easier?
The invention of the abacus.
Do you need common denominators when subtracting fractions?
Yes. You need common denominators if you want to:Add fractionsSubtract fractionsCompare fractions ("which is larger?")You do not need common denominators to multiply or divide fractions. Thus, in the case of fractions, multiplication and division is actually easier than addition and subtraction.
When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).

In solving an equation with more than one operation you must first add then divide?
Multiplication and division come first, then addition and subtraction. For example: 4 + 2 X 3 + 6 = 16 First you multiply 2 X 3, to get 6, and then you add them, left to right 4 + 6 + 6 = 16. The answer IS NOT 54 and the answer IS NOT 30. The same rule applies with division; division comes before addition or substraction. If there is both division and multiplication and/or addition and subtraction, you resolve the multiplication and division left to right first, then resolve the addition and subtraction left to right. It is generally better to user parentheses to illustrate exactly what you mean. For example, the above equation would be easier read if it was written 4 + (2 X 3) + 6. Or, if you really had wanted the addition first, (4 + 2) X (3 + 6). Then it is quicker and easier for the reader to see what is going on in equation.

How do you learn additional mathematics subject easier?
Get the basics down! Addition, subtraction, multiplication, and division are the basis for all the other maths. All the other maths are formulaes which use these four basic equations. Learn the multiplication tables and the division tables by memory because it makes it much easier. you actually need to practice frequently.... Atleast a day in solving an add-math question will help develope your brain on additional math and when you get used to it do not stop continue until you think can solve questions with ease
How can use subtraction to check addition with mixed numbers?
Subtraction is the opposite operation to addition, so can be used to check an addition by subtracting one of the addends (numbers being added together) from the total obtained to see if the other addend results. This can be used with any two addends including mixed numbers. Working with mixed numbers is often much easier (especially for multiplication and division) by converting them first to improper fractions, doing the operations and converting any resultant improper fraction back to a mixed number.
What is 16 plus 1 plus 2?
16+1+2=19 There are alot of sums to fit into this question, but these sums are much more easier with a horizontal sum. This is called BOD MAS. BOD MAS i s simply Brackets Over Division Multiplication Addition and Subtraction. Six ten plus one plus two would equal nineteen.
How complex quantity can be expressed?
Complex quantities are points on a coordinate system; the horizontal axis is called the real numbers, the vertical axis, the imaginary numbers.The point that represents a complex number can be expressed:a) In rectangular coordinates, by specifying both coordinates, for example, 5 + 3ib) In polar coordinates, you specify a distance from the origin, and an angle, for example, 10 (angle symbol) 30 degrees.It turns out that addition and subtraction are easier with rectangular coordinates, whereas multiplication, division, and therefore also powers and roots, are easier with polar coordinates.Complex quantities are points on a coordinate system; the horizontal axis is called the real numbers, the vertical axis, the imaginary numbers.The point that represents a complex number can be expressed:a) In rectangular coordinates, by specifying both coordinates, for example, 5 + 3ib) In polar coordinates, you specify a distance from the origin, and an angle, for example, 10 (angle symbol) 30 degrees.It turns out that addition and subtraction are easier with rectangular coordinates, whereas multiplication, division, and therefore also powers and roots, are easier with polar coordinates.Complex quantities are points on a coordinate system; the horizontal axis is called the real numbers, the vertical axis, the imaginary numbers.The point that represents a complex number can be expressed:a) In rectangular coordinates, by specifying both coordinates, for example, 5 + 3ib) In polar coordinates, you specify a distance from the origin, and an angle, for example, 10 (angle symbol) 30 degrees.It turns out that addition and subtraction are easier with rectangular coordinates, whereas multiplication, division, and therefore also powers and roots, are easier with polar coordinates.Complex quantities are points on a coordinate system; the horizontal axis is called the real numbers, the vertical axis, the imaginary numbers.The point that represents a complex number can be expressed:a) In rectangular coordinates, by specifying both coordinates, for example, 5 + 3ib) In polar coordinates, you specify a distance from the origin, and an angle, for example, 10 (angle symbol) 30 degrees.It turns out that addition and subtraction are easier with rectangular coordinates, whereas multiplication, division, and therefore also powers and roots, are easier with polar coordinates.
What is the fastest and easiest way to do division?
The fastest way to learn and do division is memorize your division math facts. It is easier to memorize the division facts, knowing your multiplication facts will help as well.
Why is learning math difficult?
Perhaps because there are many formulas and strategies to remember. But it gets easier the more you know. One trick is to recall that math is a language, but the rules tend to be far easier than those of "regular" languages, the syntax is simpler, and there are far fewer exceptions. The only exception I can think of offhand is that you cannot divide by zero. Oh, addition and multiplication are associative and commutative, but subtraction and division are not. Neither is exponentiation, another binary operation.
