I have been learning how to do tidy numbers. Tidy numbers is a maths strategy to use a number line to solve equations. This is how I solved the equation.
71 + _____ = 103
I jumped to 80 because that is the nearest tidy number. That is + 9
Then I jumped to 90. That is + 10
Then I jumped to 100. That is + 10
Then I jumped to 103. That is + 3
They add to 32. So the equation is 71 + 32 = 103
