## Algebra: A Combined Approach (4th Edition)

a. $m^3$ b. $3m$ c. $-m^3$ d. $-3m$
a. When multiplying monomials you multiply the coefficients and the variables, then you multiply those two products $1\times1\times1=1$ & $(m)\times(m)\times(m)=m^3$. b. When adding like terms you add the coefficients $1+1+1=3$. c. Same as a. $-1\times-1\times-1=-1$ d. Same as b. $-1+-1+-1=-3$
