1. Maraea is saving to buy a cat. In 3 weeks she has saved $9, $56 and $72. Show how to work out how much she has saved altogether.
9 + 56 + 72 =
50 + 70 = 120
6 + 2 = 8
9 + 8 = 17
120 + 17 = 137
ANSWER 137.

2. Tom saves his money each month to buy a dog. In 4 months he has saved $36, $78, $203, and $123. Show how to work out how much he has saved altogether.
36+78+203+123=?
4 from 8 then put the four to the 36 = 40.
then there will be 40 + 74 + 203 +123.
40 plus 70 = 110 + 4 = 114.
200 + 120 = 320 + 3 + 3 = 326.
114 + 326 = 440. Answer440
