Stories can help us to understand the operations that need to happen, in order to solve a problem. Have a look at this story, to remember how to write a number sentence to represent the story.
There were 11 flowers in Dave’s garden. 4 more flowers grew, then Dave picked 8 flowers to put in a vase.
Which expression matches the word problem for the number of flowers left in the garden?
Identifying the clues helps us work out how to write out our number problem. We can also look for pieces of information that may not be useful, and ignore those.
This video shows us how the order of operations is used in everyday problems.
Write the number sentence described as:
The sum of 4 and 6 is multiplied by 2.
Another word that is sometimes used for parentheses is brackets.
If we need to multiply or divide multiple numbers by the same amount, that is when we should use parentheses.
This video explains what the rules are when it comes to the order of operations.
