9 and 24
x+y=33 (Known)
x-y=15 (Known)
2y=18 (Subtract the equations)
y=9 (Solve for y)
x-9=15 (Plug y into a known equation)
x =24 (Solve for x)
That means that you calculate the cubes of two numbers, and then either add or subtract them.
well that is easy to add two whole numbers like 8+10 is just 18 so you find the total of the two numbers. then to subtract you take it away so 9-4=5 then to check add the 2nd number (in this case 4) to what the sum equals and 4+5=9

By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
When you subtract one number from another you get the difference.You just said it; sum.
The numbers are: 76 and 20
223 and 21 if you multiply them. 9366 and 2 if you divide them. 4600 and 83 if you add them. 4686 and 3 if you subtract them.
15 and 10 if you multiply them. 140 and 10 if you add them. 160 and 10 if you subtract them. 1500 and 10 if you divide them.
9 and 6 but subtract not add
