Answer:
(10,2)(20,4)(30,6)(40,8)
Step-by-step explanation:
In each bracket the first digit divided by the second is equal to 5
10÷2=5
20÷4=5
30÷6=5
40÷8=5
By moving the signs he actually changed the number itself. He changed -6 from a negative to a positive and 5 from a positive to a negative. Both equations give different answers.
Hopefully this helps :)
