2. NUMERICAL EXPRESSIONS
What's that?
It„s a when we find a:
 Operation
 Up to the real numbers R
 (Probable) Potencies
 (Probable) Square roots
 (Probable) Parenthesis, brackets, keys
 (Probable) Absolute value

5. PEMDAS
 What‟s “PEMDAS”?!
Over here we see that parenthesis, brackets and keys are
ALWAYS FIRST, no matter what. Exponents (Potency & roots) is
2 nd . Division and multiplication are the same qualification, so
they are both 3 rd .
Addition and subtraction are also the same qualification
on, so they are both 4 th .

7. ALGEBRAIC EXPRESSIONS
 What‟s the dif ference between numerical expressions and
algebraic expressions?
Numerical expressions are always with numbers, and algebraic
expressions are always with variables; but some contain
coef ficient of the variable.
