<h3>Order of Operations: </h3><h3>The steps used to evaluate a numerical expression:</h3><h3> 1) Simplify the expressions inside grouping symbols. ( ) , [ ]</h3><h3>2) Evaluate all powers. </h3><h3>3) Do all multiplications and/or divisions from left to right. </h3><h3>4) Do all additions and/or subtractions from left to right.
</h3><h3>PEMDAS represents the order of operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction</h3><h2>Example :</h2><h3>18 – (4 + 2) + (6 × 5) ÷ 3 = [Parentheses first]</h3><h3>Notice: There are no Exponents in this expression.
</h3><h3>18 – 6 + 30 ÷ 3 = [Multiplication/Division left to right next]
</h3><h3>18 – 6 + 10 = 22 [Addition/Subtraction left to right next]</h3><h3>When there are multiple grouping symbols, always work on the innermost grouping symbols first </h3><h3> ( ) = Parentheses [ ] = Brackets</h3><h3>Example: [(7 – 2) × 3] ÷ [4 + (2 ÷ 2)] – 7 × 0</h3><h3>Start with [(7 – 2)] and (2 ÷ 2) as these are the operations in the innermost grouping symbols.</h3><h3>
