Order of Operation Calculator

It is an excellent tool

This will be so helpful for the students! It's a great calculator, congratulations.

Hi Martin,

Thank you for reaching out. In Mathematics, we use the acronym BODMAS, for the order in which we do operations

Brackets

Order (e.g. x^2, y^3 etc)

Division

Multiplication

Addition

Subtraction

For the above example, we would do MULTIPLICATION before ADDITION

2*3 = 6

1 + 6 = 7

The correct answer is therefore 7. If you are unsure or have any questions, please do not hesitate to ask!

Kind regards,

Roshan :)

The order of operations are known as BIDMAS. This is used to determine what part of a mathematical sentence you do first, second and so on. B is first it is short for brackets anything in a bracket needs to be addressed first. I is indices so if you have a number that has a little number at the top right hand corner that is next, remember the indices is how many times you you multiply the digit so for an example if it is 4 with a little 3 it is 4x4x4, 4x4 is 16, 16x4 is 64. D stands for division, which is the next step, M is multiplication and finally A and S are addition and subtraction.

BODMAS stands for .Brackets, Orders, Division, Multiplication, Addition, Subtraction. So to solve 1+2*3, first comes multiplication that is 2*3=6 and then addition that is 6+1=7. So the answer is 7.

So, long ago people agreed to follow rules when doing calculations, and the rule is denoted by BODMAS:

The RULE of calculation operation is denoted by BODMAS.

Evaluate the terms in the bracket first, followed by Order (Powers and Square Roots etc.), Division, Multiplication, Addition then Subtraction.

B Brackets first

O: Orders (i.e. Powers and Square Roots, etc.)

DM: Division and Multiplication (left-to-right)

AS: Addition and Subtraction (left-to-right)

5 × 2²=5 × 4=20 Correct

  5 × 2²=10²=100 Wrong

 4 × (5 + 3)=4 × 8=32 Correct

  4 × (5 + 3)=20 + 3=23 wrong

 2 + 5 × 3=2 + 15=17 Correct

  2 + 5 × 3=7 × 3=21 wrong

 30 ÷ 5 × 3=6 × 3=18 Correct

  30 ÷ 5 × 3=30 ÷ 15=2 wrong

Cheers.

So with the bodmas rule, you have to multiply 2 and 3 first and then add it with 1.

So the answer will be 7

The correct answer is 7 According to BODMAS multiplying comes first then adding

Hi Martin,

BODMAS stands for Brackets/Order of powers/Divide/Multiply/Add/Subtract. In any Order of Operation task, you would follow this order from the acronym.

So in answer to your question above, you would Multiply the 2 and 3 together first (=6) then simply add 1 (6 + 1 = 7).

Hope that helps!

1+2*3=9 We add before we multiply

Great Resource for helping KS3 students with understanding and practicing BODMAS/BIDMAS

7 will be the Asnwer

should read 1 + (2*3). Work out the calculation in the brackets first

Does divide come before multiple

eg 7 * 9/3 - makes no difference which way round you do it

ie 63/3 is the same as 7 * 3

The answer is 7 as you multiply the two numbers before adding the final number

Division comes first before multiplication, and multiplication comes first before addition.
