Numeracy Basics | Order of Operations

Activity One: BIMDAS


1. Use BIMDAS to solve the following problems.

a. 3 + 4 x 2 – 7  
b. (25 + 3 x 5) ÷ 8  
c. 40 – 12 x (7 – 5) ÷ 8  

 

2. Lisa prints out a series of equations as answers to her mathematics homework, but realises she has forgotten to include any brackets. Put in brackets where necessary to make her statements true:

a. 8 + 4 - 3 x 2 = 10  
b. 72 ÷ 8 - 3 + 1 = 5  
c. 12 + 8 – 5 - 1 = 16  

Oh no! My brackets are gone!
