You use the order of operations witch PEMDAS It stands for Parentheses, Exponents, Multiplication,Division, Addition, Subtraction So first you do 3 X 5=6 then 6+5=11 so you end up with 10-11=-1 so the answer is -1

OK 10 - 3 x 2 + 5 .. if you do it ''in order'' gives you .. 7 x 2 + 5 14 + 5 19 ...... Yes However .. you have to do the 3 x 2 first .. 10 - 3 x 2 + 5 10 - 6 + 5 4 + 5 9 What would be completely wrong is doing the 3 x 2 last .. 10 - 3 x 2 + 5 7 x 7 49

10 - 3x2 +5 is 10- (3x2) +5 = 10-6 +5

The answer is nine because pemdas says you would do 3×2 first then since 10- and +5 you would go from left to right so it would be 10-6=4 then 4+5= 9 as your final answer

Computers use a standard for the operations of math in a statement/an equation remembered by / referred to as PEDMAS. First you do 3 x 2 ... aka 6 ... which you subtract from 10 ... = 4 ... then add 5 = 9.
