Addition and Subtraction level 3

I am able to solve addition and subtraction problems at level 3.

Addition and Subtraction.

Show how you solve these number problems.  


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. Answer-440-




3.   Te Ao is saving to buy a horse.  So far she has saved $17, $160, $72, and $148.  Show how to work out how much she has saved altogether.
17 + 160 + 72 + 148 = ?
160 + 148 = 308
17 + 72 = 89
308 + 89 = 397.
                        Answer-397-




4.  Petelo has $ 147 as a present.  He spent $78 at the shop.  How much has he got left?
100 - 78 = 22
22 + 47 = 69                          
                             Answer-69-
