precedence

 * =understand the effects of the precedence of standard operators and the use of parentheses to alter the order of precedence;=


 * ==**The order of operations is a rule used to clarify which procedures should be performed first in a given mathematical expression/equation. The order in which takes precedence is refered to as B I D M A S.**==
 * ==**For example, in computer languages multiplication is done before addition. In the expression 2 + 3 × 4=14. This means that m****ultiplication took precedence over addition, whichever side of a number it appeared on.**==
 * ==**BIDMAS stands for Brackets Indices Division Multiplication Addition and Subtracttion.**==

=__**Do things in Brackets First For Example:**__=
 * ||  || ==**6 × (5 + 3) **== || ==**=**== || ==**6 × 8 **== || ==**=**== || ==**48**== ||   ||
 * ||  || ==**6 × (5 + 3)**== || ==**=**== || ==**30 + 3**== || ==**=**== || ==**33**== || == **(wrong)** == ||

**(Powers, Roots) before Multiply, Divide, Add or Subtract. Example:**

 * ||  || ==**5 × 22 **== || ==**=**== || ==**5 × 4 **== || ==**=**== || ==**20**== ||   ||
 * ||  || ==**5 × 22**== || ==**=**== || ==102== || ==**=**== || ==**100**== || == **(wrong)** == ||

**Multiply or Divide before you Add or Subtract. Example:**

 * ||  || ==**2 + 5 × 3 **== || ==**=**== || ==**2 + 15 **== || ==**=**== || ==**17**== ||   ||
 * ||  || ==**2 + 5 × 3**== || ==**=**== || ==**7 × 3**== || ==**=**== || ==**21**== || == **(wrong)** == ||

**Otherwise just go left to right. Example:**

 * ||  || ==** 30 ÷ 5 × 3**== || ==**=**== || ==** 6 × 3**== || ==**=**== || ==**18**== ||   ||
 * ||  || ==**30 ÷ 5 × 3**== || ==**=**== || ==**30 ÷ 15**== || ==**=**== || ==**2**== || == **(wrong)** == ||
