Answer:
A is 64 and b is 34
Step-by-step explanation:
That would be 4 thousands
The value of 1 in 178 is 100 since it is in the hundreds place. The value of 7 in 178 is 70 and the value of 8 in 178 is 8. The hundreds place carries numbers from 1 to 9. Once you get to 10, you add a digit to the number such that you now have four total numbers and the first digit is in the thousands place.
So it’s -3 and the second one is +4
