**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

**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.**

*basic operators*- Exponents (index) and roots
- Multiplication and division
- Addition and subtraction

**BODMAS**, which stands for Brackets, Order, Divide, Multiply, Add, Subtract. It would be easier if BODMAS was recognised worldwide, but unfortunately it isn’t.
