It is an unknown variable
The Baby Trend Sit N Stand Plus weighs 30lbs.
The n is an unknown variable.
5+n+3 = 8+n
7n+10
3n + 9 = 3(n + 3)
They have n in common.
That would be 18+n. 5+3+2 = 5+3+n 10 = 8 + n 10-8 = n 2 = n and if you substitute 2 for n then you see that 5+3+2 = 5+3+2
Yes it does. Very good !
(n2 + n)/2 1+2+3+4+5+n= 15+n
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
If these expressions are stand-alone (not nested), then they do the same thing, ie increment 'n'.
