How to evaulate the expression using order of operations

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

1.) 18+5 is one way i’m pretty sure there are others but i can’t think of them right now
