MGSE6.EE.2c. Evaluate expressions at specific
values of their variables. Include expressions that
arise from formulas used in real-world problems.
Perform arithmetic operations, including those
involving whole-number exponents, in the
conventional order when there are no parentheses
to specify a order (Order of Operations).

An Algebraic Expressions is formed with a constant
and a variable for example: x + 26 where x is the
variable and 26 is the constant. Each constant and
variable are called terms when added or subtracted.

In algebraic expressions, multiplication and division are usually
÷ and ×.
 For example, write 3× n as 3n, 3 ∙ n or n ∙ 3.
