Hey mathmations are back and we are teaching you how to round to check your answers .
explanation:
what is 142+523=
If your not sure then you round your numbers to the nearest 100 and then add it together .142 rounded to the nearest hundred is 100 and then 523 rounded to the nearest hundred is 500 then you add them together.
add 100 and 500 together which is 600 Then add 142 and 523 together and it’s 665 because it’s close together you then know it’s correct.
Thats it today from the mathmations signing out till next time bye for now;).
