Question

What is the compensation strategy for 39+54

Answer 1

The compensation strategy is a method making an operation (adding and subtraction) simplier.

From the problem :

`39+54`

Add 1 to 39, this will become 40

`40+54=94`

Then subtract 1 to the answer to make inverse or reverse the number that you added earlier.

`94-1=93`

The answer is 93
