Sometimes you can think of things instead of letters, for example...
3a + 2a = ?
If that was 3 apples plus 2 apples equals ... ? then you could do it, right?
3 apples + 2 apples = 5 apples
3a + 2a = 5a
And the same with MINUS...
10b - 7b = ?
10 bananas - 7 bananas = 3 bananas
10b - 7b = 3b
Of course, you can't add bananas and apples, you have to count them separately, so...
3a + 4b + 7a - 2b
= 3 apples + 4 bananas + 7 apples - 2 banana
= 10 apples + 2 bananas
= 10a +2b
(You can't add these two together)
After that it gets more complicated...
