A negative index indicates that the value is a reciprocal of the number.
Write the number as a denominator, changing the negative index to a positive index. Set the numerator to 1.
For example, 2-2 can also be written as `frac(1)(2^2)` which evaluates to `frac(1)(4)`.
Calculate 42 ÷ 26. Write the answer as a fraction.
Rewrite the question as (22)2 ÷ 26
Evaluate to 24 ÷ 26
= 2(4-6)
= 2-2
= `frac(1)(2^2)` = `frac(1)(4)`
Answer: `frac(1)(4)`
Calculate 52 ÷ 5-2.
5(2 - -2) = 54.
