the answer would be as many times that you need to express each variable

n × a = ?
lets say n = 3 and a = 5.
That would make n × a this, 3 × 5.
First lets solve 3 × 5.
3 × 5 = 15
So, if were to solve 3 × 5 using only addition it would be like this
3 + 3 + 3 + 3 = 15
OR
5 + 5 + 5 = 15
So, an equivalent expression for n × a using only addition can be
n × a
n + n + n + n
