3p+2p-p simplified
( on mathwatch)

4p

Step-by-step explanation:

To simplify this expression, just add/subtract as normal.

3p + 2p - p

3p + 2p = 5p

5p - (1)p = 4p

4p is the simplified version of 3p + 2p - p.

4p

Step-by-step explanation:

You have 3p + 2p - p

If there is a single alone p like on the end of the equation, it can be assumed that there is a 1 in front of it, even if it doesn't show it.

A letter variable that is alone means there's always like an invisible 1 in front. So, you have:

3p + 2p - 1p

Subtract 1p from 2p to get 1p, or just p.

3p + p

=4p
