90 times (8 times 10^9) Correct?
Remember the order of operations "Please Excuse My Dear Aunt Sally", PEMDAS:
- Parenthesis (brackets if you are in Canada, Australia or the UK)
- Exponents - this includes roots and powers
- Multiplication
- Division
- Addition
- Subtraction
In your problem:
10^9 (use your calculator) then multiply times 8 and the product times 90
