Basic Arithmetic Practice
Maths Basic Arithmetic Code 0BAB Bodmas and Pemdas are acronyms that can help us to remember the order of operations in mathematics. They are the correct sequence to solve expressions with multiple operations in them. B rackets (parentheses) O rders (exponents) D ivision M ultiplication A ddition S ubtraction *** P arentheses (brackets) E xponents (orders) M ultiplication D ivision A ddition S ubtraction *** Three-Step Process to solve problems: Scan, Solve, Rescan; • Scan: read the expression left-to-right to identify the highest priority operation. • Solve: this singular expression, creating a new expression. • Rescan: the newly created expression, can be solved. ** Remember: multiplication outside of brackets (parentheses) does not get priority over division elsewhere. ** Example: 8+3×4= Incorrect: 8+3×4=44 (8+3=11, 11×4=44.) Correct: 8+3×4=20 (3×4 is the priority, the new expression becomes 8+12). High School Level Foundational Tier Questions (Non Calculator) 1. 4+5×3-2= 2. (8-3)×2...
