Mathematical Expressions and Formulas

الدرس ده محتاج حساب

A numerical expression contains only numbers and operations; an algebraic expression also contains variables. An equation links two expressions with $=$, an inequality with $<,>,\le,\ge$, and a formula states a rule such as $A=l\times w$. Like terms (same variables and powers) can be added, which — together with the distributive property — lets us write an expression in its simplest form.
