What is Addition?

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

Given there are 40 black balls this is 4 more than twice the number of yellow balls. Therefore, we can write,

Number of black balls = Number of yellow balls + 4

40 = Number of yellow balls + 4

Number of yellow balls = 36

Hence, the number of yellow balls is 36.
