Maths homework challenge



For homework this week we had to solve this problem and this is how I worked it out. The question was The dairy owner had 73 Powerade bottles left. Then she sold 29. How many has she got left?






The question is asking 73-29=?

This is how I worked it out.

70-20=50
53-9=44

73-29=44


How I checked it

29+1=30
30+40=70
70+3=73
40+1+3=44
Mr.M said that we can mix all the numbers up to fit where we are learning so that is what I did.

730-92__

This is how I worked it out.

730-90=640
640-2=638

730-92=638
