Suppose that n and a are two real and integers.
 We have then that we can rewrite an expression of the form:
 [tex] n * a [/tex]
 As the sum of "a" times "n".
 For example:
 For n = 4 and a = 3 we have:
 [tex] 4 * 3 = 12 [/tex]
 Equivalently we have:
 [tex] 4 * 3 = 4 + 4 + 4 = 12[/tex]

Answer:

Equivalent expression for n x a  = a+ a+a+a....n times

Step-by-step explanation:

Given: Expression for n x a .

To find : Write an equivalent expression for n x a using only addition.

Solution : We have given that n x a .

Here, we can say Sum of  a is n times.

We can rewrite it n x a  = a+ a+a+a....n times.

Example : 3 x 2 = 2 +2+ 2.

                   6 = 6 ( true)

Therefore , equivalent expression for n x a  = a+ a+a+a....n times.
