The two numbers that add up to 7 and multiply to 9 are 3 and 4. This is because 3 + 4 = 7 and 3 * 4 = 12, not 9. To find the numbers that multiply to 9, we need to factorize 9 into its prime factors, which are 3 * 3. Therefore, the numbers that add up to 7 and multiply to 9 are 3 and 4.

They can be: 73+7 = 80
How about 7 times 7 = 49 as one example

List numbers that multiply to make 28 and find their sums. Since negative times a negative is positive, list the negatives. -1, -28 = -29 -2, -14 = -15 -4, -7 = -11 Aha! -4 and -7 multiply to make 28 and add to -11; therefore, -4 and -7 are the two numbers.
They can be: 73+7 = 80
To find numbers with a mean of 7, we need to consider the sum of the numbers and the total count of numbers. If we have two numbers, they must add up to 14 to have a mean of 7. For three numbers, their sum must be 21. In general, any set of numbers that sum up to 7 times the count of numbers will have a mean of 7.

You can, if you have a square with side 5 you can multiply 5*5=25 or you can add 5+5+5+5+5=25 If you want to do this just take one of the numbers and add it to itself the other numbers times. so if you have 7*8 you add 7 to itself 8 times, so add 8 7's 7+7+7+7+7+7+7+7=56 or add 7 8's 8+8+8+8+8+8+8=56 Multiplying is much easier.
