Theory

Add and subtract terms

Terms are numerical or algebraic expressions that are added or subtracted. If the terms are algebraic the operations are performed by combining like terms.

3 x^{2} + 3 x - 4 - 2 x + 3 + 7 x^{2} = 10 x^{2} + x + 1

Here, that means that the

x^{2}

-terms,

x

-terms, and constants are added separately.
