Order of Operations (PENDAS/BODMAS)

Can you answer this? 7 - 1 × 0 + 3 ÷ 3 = ? In arithmetic, there are two types of components: the numbers themselves and the operators (also called operations) that tell you what to do with those numbers. The basic operators in arithmetic are addition (sum), subtraction (difference), multiplication (product) and division (quotient). So, in the sum 7 × 3 + 5 there are three numbers; 7, 3 and 5 and two operators, a multiplication (×) and an addition (+). The order of operations used throughout mathematics, science, technology and many computer programming languages is expressed here.
  1. Exponents (index) and roots
  2. Multiplication and division
  3. Addition and subtraction
The definitive order of operations is summed up in the acronym BODMAS, which stands for Brackets, Order, Divide, Multiply, Add, Subtract. It would be easier if BODMAS was recognised worldwide, but unfortunately it isn’t. Whole numbers - BODMAS
