Here's one way to work that out. Let's call the numbers "a" and "b" We're told:
a + b = 23
ab = 108
We can take one of those two, solve it for either a or b, substitute it into the other, and solve for the other variable using our new equation:
a + b = 23
b = 23 - a
∴ a(23 - a) = 108
-a2 + 23a = 108
a2 - 23a + 108 = 0
a2 - 23a + (23/2)2 = (23/2)2 - 108
(a - 23/2)2 = 529/4 - 432/4
(a - 23/2)2 = 97/4
a - 23/2 = ± √(97/4)
a = (23 ± √97) / 2
So the two numbers that meet this condition are (23 - √97) / 2 and (23 + √97) / 2
It is 3 time 7 = 21
They are the product of the number of possible outcomes for each of the component events.
The product of 4 and 3 is 12. You can use a calculator or you could do 4+4+4= or 3+3+3+3= and you will get 12. The properties of multiplication is that if you switch the beginning two numbers around, the product of the two numbers will not be impacted by the change.
Prime numbers are helpful in cryptography because it is MUCH easier to calculate the product (multiplication) of two prime numbers than to do the reverse process (find the prime factors of a big number). The bigger the prime numbers are, the higher the difference in time between calculating the product, or factoryzing this product back into the two prime numbers. When person A wants to tell B a secret, they could agree on two great prime numbers (in a secret way) and later use the product to communicate. A and B could easely calculate the other's factor because they know their own factor. Anyone else would have to try to factorize the huge prime number without any knowledge which would take, ideally, longer than 4.6 billion years (the age of the Earth). This is a VERY simplified answer and more can be found by googling around.
NegativeIf the two factors have the same sign, their product is positive.If the two factors have different signs, their product is negative.
The following rules apply to all real numbers.if either number is zero, then the product is zero.if the signs of two numbers are the same, their product is positive; if the signs are different then the product is negative.for the product of three or more numbers, the associative property can be used to find the product two-at-a-time.
Not always, but most of the time.
It is 3 time 7 = 21
negative time negative equal positive
If the product of the two numbers is the sum times 24, then the product of the two numbers is 2400. 40 times 60 is 2400, and 40 plus 60 is 100. The two numbers are 40 and 60.

same results every time
Not all the time, 11 x 3 = 33
is a game in math that is fun and stupid at the same time
yes
4 and 6 6 and 8 Any time the two numbers have a common factor, their LCM will be less than the product because the common factor contributes to the LCM fewer times than it contributes to the product.
As a product of its prime factors: 2*3*3 = 18
