For subtracting and adding you cannot add or subtract unalike things. For multiplication and division you can multiply by whatever you want. In some maths you even multiply by variables such as "x". Or divide by them.
It is: (9-5)*6*1 = 24

because it is easier than adding and subtracting so many times??
You divide exponents by simply subtracting the exponents. You multiply exponents by adding them together. You can test your answers by doing long math.
First you work our how much to divide multiply by ( 1000,100,10 ). Then u add or subtract the amount

The main four operators are: Plus (+) Minus (-) Multiply (*) or (x) Divide (/) or (÷)
It is called algebra. When two quantities are related as long as you do the same operation to both (add, subtract, multiply, or divide) you do not change the relation
There are different symbols for multiply, dividing and subtracting. You can use the symbols like "x, / and -".
None. It is more like adding.
Around the ages of 14 - 15 years (But I don't know what grade that is, since I was a UK student. They use "years" instead of grades).
For dividing they spelled it out for example, two-sevenths was "duae septimae" and three-eighths was "tres octavae." For multiplying they put horizontal a dash or line over the numeral and multiply by a thousand ...... I believed there was nor subtracting or adding just adding on or taking off numerals.
* Begin by subtracting 32 from the Fahrenheit number. * Divide the answer by 9. * Then multiply that answer by 5.

They were able to convert the process of multiplication (or division) to addition (subtraction). This allowed large amounts of work to be delegated to clerical staff who were competent at adding and subtracting and a lot cheaper than people who could multiply and divide efficiently.
Start by subtracting 32 from 90. Then multiply the answer with 5 and divide by 9. In this case the answer is 32.22 degree Celsius.
Start by subtracting 32 from -2. Then multiply the answer with 5 and then divide it by 9. So, in this case the answer is -18 degree celsius.
Start by subtracting 32 from 77. Then multiply the answer with 5 and divide by 9. In this case the answer is 25 degree Celsius.
Start by subtracting 32 from 49.7. Then multiply the answer with 5 and then divide by 9. In this case the answer is 9.8 degree celsius.
When multiplying fractions, the fractions do not have to have the same denominator as when adding or subtracting. You just multiply the numerators and multiply the denominators, then reduce if necessary.Example : 3/4 x 5/7 -- multiply 3 times 5 and 4 times 7 = 15/28Example : 2/3 x 6/7 -- multiply 2 times 6 and 3 times 7 = 12/21* In this case, you can divide by 3/3 to reduce the fraction to 4/7
Adding negatives? You get a negative. But if you multiply/divide 2 negatives, that's a positive.
You can multiply to get the closest possible answer and then subtract and whatever you got from subtracting subtract it by how many times you can multiply the divisor.
