The expression "a number n increased by nineteen" can be represented mathematically as n + 19. This expression indicates that you are taking a specific number, n, and adding nineteen to it. The result of evaluating this expression would be the sum of n and 19.
N + 6
n+m
3n + 15 equals 3 times the number n, the answer to which is increased by 15. It can only be evaluated if the value of n is known. The expression can be factorised but that is of marginal help in evaluating it.
n + 6.2
n + 25 =====
8+n
n/6 + 3
-8 + 13/N, where N ≠0.
n+7 or X+7
N + 6
n+81
Un = n + 32
If you call the number "n", then the expression would be "n+5".
nineteen
31 plus n
Nineteen is spelled as N-I-N-E-T-E-E-N.
