What is Bodmas rule?

What is Pemdas example?
PEMDAS Example 05: 8 x 8 ÷ 16 Remember that PEMDAS requires you to solve Multiplication/Division from left to right based on whichever comes first. In this example, when moving from left to right, multiplication comes first so you would first perform 8 x 8 = 64.
Why do you multiply first then add?
– Because multiplication is more powerful than addition. We always do what is more powerful first. Any other ideas to add to that? – It’s repeated addition so we can break down to an easier way to understand.
What comes first adding or subtracting?
Many students learn the order of operations using PEMDAS (Parentheses, Exponents, Multiplication, Division…) as a memory aid. This very often leads to the misconception that multiplication comes before division and that addition comes before subtraction. Understanding the principle is probably the best memory aid.
