For example, 4x and 7x are like terms because the variable x is the same in both. The variables have to be exactly the same. 4x and 4x^2 are not like terms because their variables are not exactly the same. The coefficients do not have to be the same. Adding Monomials Subtracting ...
just as you manipulated constants when you first learned arithmetic. Dividing polynomials might seem like the most intimidating of the operations to master, but as long as you remember the basic rules about adding and subtracting fractions and simplifying them, it's a surprisingly...

Well, for example, adding the two complex numbers (3 - 2i) and (-5 - 4i) is as easy as adding 3 and -5 to get -2, then -2i and -4i to get -6i. This makes our answer -2 - 6i. That's it! Subtracting Complex Numbers Multiplying Complex Numbers Lesson Summary Lesson ...
Adding and Subtracting with Non-like Terms When a problem gives you two terms, or chunks, that do not have the exact same variables, or letters, raised to the exact same exponents, you cannot combine them. For instance, (4x^2)(y^3) + (6x^4)(y^2) ...
