L.I, to add numbers by making tidy numbers
Today I learned about tidy numbers for example the numbers ending in 0, like 10, 20, 30, and 40. I had to add numbers together by using tidy numbers. Here is an example:
9 + 3 =?
The closest tidy number is 10. You have to take one away from the 3 and add it to the 9. There is 2 left and the 9 turned to 10 which makes it 10+2=12.
It was hard to make the tidy numbers.
