The factor pairs of 210 are (210,1)(105,2)(70,3)(42,5)(35,6)(30,7)(21,10)(15,14)
None of them add up to 23. If that was -210, you could use 30 and -7.

The numbers are: 21 and -10
The two numbers that multiply to make 40 and add to make -13 are -8 and -5. When you multiply -8 and -5, you get 40, and when you add them together, you get -13.
The numbers that multiply to make 84 and add to make 5 are 12 and -7. When you multiply 12 by -7, you get 84, and when you add them together, 12 + (-7) equals 5. Thus, the solution is 12 and -7.

The numbers are: -5 and 3
To find three numbers that add to 630 and can be represented using multiplication, consider the numbers 210, 210, and 210. While these three numbers add up to 630 (210 + 210 + 210 = 630), their product is (210 \times 210 \times 210). However, if you're looking for a multiplication factor, you could consider (1 \times 1 \times 630) or any variation thereof, where two of the numbers are 1 and the third is 630.
-5 and +3
That depends whether you want to add the numbers, to multiply them, or what.
The two numbers that multiply to -15 and add up to 2 are 5 and -3. When you multiply 5 and -3, you get -15, and when you add them together, you get 2.
