Question

What's 2 (n+3) in words

Answer 1

two times a number n plus three

Answer 2

Since the 2 multiplies the whole parenthesis, you have to add n and 3, and then double the whole result.

For example, if $n=6$, you first have to perform $6+3=9$, and then double the result: $2\times 9 = 18$

So, in words, you can descrive this steps as "twice the sum of a number n and 3"
