    like terms; examples: \(\large\color{black}{ \displaystyle 2x^2+3x^2=5x^2 }\) \(\large\color{black}{ \displaystyle 9x^w-8x^w=1x^w=x^w }\) \(\large\color{black}{ \displaystyle 2y-5y=-3y }\) \(\large\color{black}{ \displaystyle 14+13=27 }\)

    those are examples of the terms you can combine (their coefficients - the numbers in front of the variable - don't matter. And the like term is defined if there is a same variable and it is raised to the same power.)

    but you can NOT combine (examples) \(\large\color{red}{ \displaystyle 3x^4+2x^3 }\) (although variable is same, the powers of x are NOT the same) \(\large\color{red}{ \displaystyle 2x^p+3a^p }\) (although the powers of the variable are the same (power of p), because variables are NOT the same.) \(\large\color{red}{ \displaystyle 5+3x }\) (one term contains variable, the other term does not)
