Compatible numbers are normal numbers that is close place value numbers. Compatible numbers only use addition and subtraction but it only suppose to have one subtraction. here's an example
The Question: 9+5+1-6= Solving the Question: 10+5=15-6=9
How to work the question is you have to redo the question but you need to start with the tidy number by adding 1 to 9 and plus the odd number and then put the take away. Add them together and subtract it and put the answer in that's all you need to do
Examples:
1. 7+3+5-10= Solving the number: 10+5=15-10=15
2. 4+2+7-6= Solving the problem: 6+7=13-6=7
