Explain why does addition works?
Addition works because like all mathmatics as long as you know 1/2 of the equation, answer, and type of equation (addition,subtraction,multiplication, or division) there is only 1 answer.
What does the math term order of operations mean?
Order of operation means that you go from the left of your equation to the right always doing multiplication and division first and then addition and subtraction
What is 1 plus 1 plus 1-1 plus 1x0?
Multiplication and division first, addition and subtraction second. Without brackets, that equation equals 2.
What is 10-3x2?
Well, if you take the rule of PEMDAS (Parenthesese, Exponent, Multiplication, Division, Addition, Subtraction) and apply it to the equation you should see this: 10-3x2 = 10-6 (because 3 times 2 is 6) =4
What is the purpose of PEMDAS?
The purpose of PEMDAS is to provide a standardized order of operations for mathematical calculations. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Following this order ensures that mathematical expressions are evaluated correctly.
What does an equation and an inequality have in common?
They both have variables. They both have addition, subtraction, multiplication, and division.
What equation is first in a system?
bedmas is what I was taught in school. It stands for brackets, ????, division, multiplication, addition, and subtraction
What is the meaning of the given letters GEMDAS?
GEMDAS stands for Given,Equation,Multiplication Division,Addition,and Subtraction
Properties used to solve equation?
Addition and subtraction property of equalityMultiplication and division property of equalityDistributive property of multiplication over additionAlso,Identity property of multiplicationZero property of addition and subtraction.

Multiplication and division first, addition and subtraction second. Without brackets, that equation equals 2.
What are the bidmas symbols?
BIDMAS stands for "Brackets, Indices (or Exponents), Division and Multiplication, Addition and Subtraction." It is a rule that dictates the order in which mathematical operations should be performed in an equation.
Why are subtraction addition multiplication division called reciprocal or inverse operations?
The inverse operation of addition would be subtraction. The inverse operation of subtraction would be addition. The inverse operation of multiplication is division and the inverse operation of division is multiplication. It is called the inverse operation because you are reversing the equation. If you add, subtract, multiply, or divide the same number on each side of the equation, then the equation would still be true. As long as you are doing the same thing on BOTH side of the equation. The reciprocal is used for dividing fractions. All you have to do for finding the reciprocal of a fraction is flip the fraction. Ex: The reciprocal of 1/4 is 4. The reciprocal of 5/8 is 8/5. You can check by multiplying the two fractions. It will equal to one if you did it right. I hope this helped a little bit.
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.
Define order of operations?
The order in which you should solve an equation to get the right answer. Use P.e.m.d.a.s. or : (1st)Parentheses, (2nd) Exponents, (3rd) Multiplication, (4th) Division, (5th) Addition, and (6th) Subtraction
Does 2x plus 3 equals 6 require addition and division?
Solving this equation for x actually requires subtraction and division rather than addition and division.
