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. Answer-440-
