Hi there,
I believe there are 3 questions.
- 2+5=8-1 It is true because 2+5 is 7 and 8-1 is 7. So, both sides have same value which means they are equal.
- 4+2=9-1 It is false because 4+2 is 6 and 9-1 is 8. So, the values are different.
- 13-0=12+1 It is true because 13-0 is 13 and 12+1 is 13. Both values are same. Therefore, they are equal.
Hope it helps :-)
