In Math Problems Do You Multiply First. Because exponents hover above the numbers, that should help you remember that they are important. For instance, 15 ÷ 3 × 4 is not 15 ÷ (3 × 4) = 15 ÷ 12, but is rather (15 ÷ 3) × 4 = 5 × 4, because, going from left to right, you get to the division sign first.

That Is What They Are There For!
When doing computations, always follow the order of operations and always perform the operations according to the following rule. The computer follows pedmas (division before multiplication) 2 (3/4) 6 = 9 or do with the rule (md) which means ``whatever comes first ((2*3)/4)*6 = 9 humans (and most recommendations, like professional societies like ams follow pemdas, which means you first do multiplication and then division (2*3)/(4*6) = 1/4 but it does not make sense to follow a. Finally, she did subtraction, by subtracting 3 from 25 to get 22.

In the case of mixed fractions, simplify it. If that number is even, divide it by 2. From what we can observe, sally did multiplication first, by multiplying 2 and 10.
Height = 20 × 2 − (1/2) × 9.8 × 2 2.
Multiply it by 7, 11, and 13. Brackets/parentheses always come first and exponents come second. We had to add 2+1 before we could multiply because of the parentheses.
If It's Odd, Multiply It By 3 And Add 1.
