Do You Multiply Before You Add In An Equation? Multiplication and division must be completed before addition and subtraction. 2 + 3 x 7 = 2 + 21 = 23 is the correct answer to the above question.
Do you add or multiply first in equations? Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.
Why is multiplication done before addition? Students should have answered something in their own words that gets across the concept: Multiplication and division are done before addition and subtraction in order to convert groups of items into subtotals of like items that can be combined for the total.
Do you multiply first if no brackets? Because there are no parentheses and exponents, start with the multiplication and then division, working from left to right.

What is the formula of BODMAS?
The BODMAS rule states we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).

Why BODMAS is wrong?
Its letters stand for Brackets, Order (meaning powers), Division, Multiplication, Addition, Subtraction. It contains no brackets, powers, division, or multiplication so we’ll follow BODMAS and do the addition followed by the subtraction: This is erroneous.

What is the golden rule for solving equations?
Do unto one side of the equation, what you do to the other!
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
