In other words the process done to the input to get the output.

2

Find the function (f):
3 ~ (- f) ~ -225

f = 288

Method:
(-225 - 3 = -288 {positive so remove negative})

3 ~ ✨- 288✨ ~ -255

3

Find the function (f):
56~ (÷ f) ~-4

f = ÷ -14

Method:
56 ÷ -4 = -14

56 ~✨÷ -14✨ ~ -4

4

Fill in the function (f):
7 ~ - f³ ~ -20

f= 3³

Method:
7 - (27) = -20
3√27 = 3
f = 3³

7 ~ ✨- 3³✨ ~ -20
