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. 3x^2+3x - 4 - 2x +3+7x^2 =10x^2+ x+1 Here, that means that the x^2-terms, x-terms, and constants are added separately.
