Explain how you would round the numbers 33 and 89 to estimate their sum

33 rounded would be 30 because the 3 is less than 5 so it stays the same. 89 would round to 90 because the 9 is bigger than 5 so the 8 turns into a 9 then add 30+90=120

You would round them to the nearest ten. First 33 you would take the 3 in the ones place and if its greater or equal to 5 it bumps the number in the tens up but it isnt so the 3 stays the same and its 30. You do the same with 89 and get 90. That was a bit confusing but its kinda hard to explain:(
