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
