Question

How do you simplify `2^3 ÷ (7 ÷ 7 ÷ 8)` using order of operations?

Answer 1

The final answer would be 64. We figure this out through the use of BIMDAS (Brackets, Indices, Multiplication/Division, Addition/Subtraction)

Explanation:

Begin with what is inside the brackets `(7-:7-:8)`. This will equal 0.125 or `1/8`. This will give us `2^3-:0.125`.

Next we deal with indices, which in this case is `2^3`. If we expand this we get `2*2*2` which will equal 8.

Now we are at `8-:0.125` or `8-:1/8`

This will produce a result of 64.
