Question

What do u get if u times 3 by a billion and then take away 754 then times by 2

Answer 1

Here is the equation:

$3 \times 1,000,000,000 - 754 \times 2$

Use PEMDAS

$Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction$

The order for addition and subtraction doesn't matter. You do the one in the beginning first. Start with multiplication.

$3 \times 1,000,000,000 = 3,000,000,000$

Do the next part with multiplication:

$754 \times 2 = 1,508$

Subtraction is at the end, so you do it last. Subtract:

$3,000,000,000 - 1,508 = 2,999,998,492$

Your answer is 2,999,998,492
