Simplifying can refer to:

Example of reducing the number of terms

Simplify:
1*x + 3 - 4*x + 8

Add terms.
=5*x + 11

Example of reducing the number of factors

Simplify:
2*3*7*x

Multiply factors.
=42*x

Example of multiple forms of simplification

Simplify:
\frac{12*7*x-4*x}{3*2*x+5*x+9*x}

Multiply factors.
=\frac{84*x-4*x}{6*x+5*x+9*x}

Add terms.
=\frac{80*x}{20*x}

Write the numerator and denominator as products of their prime factors:
=\frac{2*2*2*2*5*x}{2*2*5*x}

The common factors are 2, 2, 5 and x. Divide numerator and denominator by 2*2*5*x:
= \frac{2*2*x}{1} = {2*2*x}

Multiply factors.
=4*x

Example of Simplifying Algebraic Expressions

-2(x-9)/6 + 9(b-x-y)/7

-2x+18/6 + 9b-9x-9y/7

-2x + 18 + 9b - 9x - 9y/42

-11x+18+9b-9y/42
