- How do we add terms such as "#axpr01#" and "#axpr02#"?
-
- Do you remember the rule: #stra*x+b*x# = #str(a+b)x#?
-
- The distributive property says that (a + b)x = ax + bx. If we turn that around, then something like 2y + 7y is the same as (2 + 7)y.
-
- Add or subtract terms containing "#axpr01(litprt)#" by adding or subtracting their coefficients to make one coefficient for "#axpr01(litprt)#".
