Maths

 What we did with Mr tisch he tort us how to round up number to the nearest 10 100 1000. For example 52 if the 2 is under 5 then it will be 50 but if it above 5 then it will be 60. Heres another example 210 see how the the 1 is under 5 and the 0 is under 5 then it will be 200 because the numbers 1 and 0 are under 5 so we take them off.
