Welcome to this SATs Maths preparation activity!
In this activity, you will use 'BODMAS'.
What is BODMAS?
BODMAS is an acronym, meaning each letter stands for a different mathematical operation.
The reason we have BODMAS is so that we can remember the order in which to carry out different operations, when solving a calculation.
Here is what BODMAS stands for:
B = Brackets
O = Order, these are square roots or indices.
D = Division
M = Multiplication
A = Addition
S = Subtraction
Division and Multiplication have the same level of order so complete from left to right, as they appear.
Addition and Subtraction have the same level of order so complete from left to right, as they appear.
Sometimes, we have to complete a number sentence with several different operations in so it's very important to know which order to complete them in.
7 + 8 x 3 = ?
Step 1: Complete the multiplication first = 8 x 3 = 24
Step 2: Next complete the addition = 7 + 24 = 31
Answer = 31
Over to you now to have a go at using BODMAS.
