Algebra.
8 - 1/3
An algebra expression is 2 or more terms which does not contain an equality sign as for example 2x+y-3z
Algebra is basically arithmetic with variable expressions, trigonometry comes after algebra because you need algebra to understand sine, cosine, tangent, as well as secant, cosecant, and cotangent.
they are the simple rules in algebra which make calculations a lot easier
Algebra
expressions don't have an equal sign and equations do
a verbal expressions is a math questions .for example 8+6
10 + B

It depends on how far you are on Pre-algebra. If you don't know anything, I recommend you take Pre-algebra 1. If you are advanced in Pre-algebra and you know variables and expressions then I recommend you take Pre-algebra 2

No, expressions cannot have the same value in algebra. They may be assigned to different values and on solving we can get different answers in each case.
