Solve
Remember the order of operations,
- parentheses
- exponents
- multiplication
- division
- addition
- subtraction
Go from top to bottom as most to least important. Start with exponents, the tiny floating numbers. 10 to the power of 5 is the same as 10 times itself 5 times, or increasing the zeros 5 times.

Next, multiply by 868.
