3 and 25
1 x 75 3 x 25 5 x 15
Multiply the first two numbers first. Then multiply the result with the third number.
The answer is 450. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
375 = 75 X 5(product is the result when you multiply the multiplicand and multiplier)
-97
1209
It's unclear whether you want two numbers that add to a sum or multiply to a product. 25 x 4 = 100 25 + 75 = 100
-5 and -15 because -5 + -15 equals -5 - 15 which is -20 and -5 multiplied by -15 = 75 (two negatives multiply to make a positive)
3 and 25
Try: 2.539014933 and -29.539014933
None of this works. There aren't two prime numbers that multiply to 75 and the only two that add to it are 73 and 2. There aren't two prime numbers whose difference is 19. Two numbers that satisfy those conditions are 47 and 28, but 28 isn't prime.
2 x 75 = 150
How about: 3*25 = 75 as an example
1 x 75, 3 x 25, 5 x 15
1 x 75, 3 x 25, 5 x 15.
1 x 75, 3 x 25, 5 x 15.
