The following are just a few examples:
10 + (-20) = -10
20 + (-30) = -10
25 + (-35) = -10
100 + (-110) = -10
-28
65
10 and 7
10 and 7 since 10x7 = 70 and 10+7 = 17
The numbers that multiply to 40 and add to -10 are -8 and -5. When multiplied together, -8 × -5 equals 40, and when added, -8 + -5 equals -10.
The two numbers that add to -16 and multiply to 60 are -10 and -6. When you add them together, -10 + (-6) equals -16. When you multiply them, -10 × -6 equals 60.
-10 and 1
First it adds by 3. Then on 4, 8, 12 it adds by 4. On 5 and 10 it adds by 5. So i guess it is 3, 4, 5.
70
First it adds by 3. Then on 4, 8, 12 it adds by 4. On 5 and 10 it adds by 5. So i guess it is 3, 4, 5.
10 and -9
