The expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.
It is defined as the combination of constants and variables with mathematical operators.
We have:
= b+b+b+b+b
Here, b is the variable after adding b five times we get:
= 5b
5 is the coefficient and b is a variable.
Thus, the expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.
