Kaleb changed the subtraction in the expression to adding the additive inverse. What was his error? 6-17-6+17
Kaleb reversed the order of the integers.
Kaleb took the additive inverse of the second integer.
Kaleb took the additive inverse of the first integer.
Kaleb replaced subtraction with addition.

Kaleb took the additive inverse of the first integer.

Step-by-step explanation:

The subtraction: 6 - 17, can be changed to: 6 + (-17), adding the additive inverse (the minus sign of the subtraction changes to a plus sign, and 17 changes to its additive inverse, -17).

Kaleb transforms: 6 - 17, into: -6 + 17. He took the additive inverse of the first integer, instead of the second one.
