The expression we have to solve is:
And we need to solve this without adding.
To solve this without adding the numbers, we note what we have here is a sum of multiple times the same number, in this case, the number is 8.
We can simplify using multiplication. To convert the expression into a multiplication, we count how many times is the number 8 in the expression.
Since it is added 5 times, we simplify it as follows:
And by making this multiplication instead of the initial addition, we find the answer:
Answer: Using multiplication 8x5=40
