The answer is 55… I’ll wait

Here is an apptdescription that caught my eye. The problem is not so much with the description as it is with what the description is telling you to do. When did simple subtraction become so complicated? 

 

Subtract Eggs app can help kids to know how to borrow when subtracting , this app use hatch out ducks to help kids understand subtraction.
For example: 82-27 =?
you can follow the steps to do subtraction by regrouping:
1. 2 is less than 7, so we need to regroup 1 ten as 10 ones, drag 1 ten to ones’ blue box.
2. After regroup, there are 7 tens and 12 ones.
3. Drag the eggs to the marked place to hatch out 7 ducks
4. Drag the 2 tens eggs to the marked place to hatch out 20 ducks
5. Check the remaining number of eggs, enter the answer, press the green check button, check the answers
