Because that's how the addition and multiplication functions were defined.
You multiply them.You multiply them.You multiply them.You multiply them.
The two numbers that multiply to get 13 are 1 and 13. Since 13 is a prime number, it cannot be factored into other whole numbers. Therefore, the only pairs that work are 1 and 13, or their negatives, -1 and -13.
multiply them together which is 25.6*1.6 = 40.96
you can use the "foil" method. this is where you multiply the first numbers in each bracket ("f") then times the outside numbers in each bracket together ("o") then multiply the inside numbers together ("i") and then, the last numbers in each bracket ("l") you then add all of the answers together and simplify it.
asked to work out the product of two or more numbers, then you need to multiply the numbers together. If you are asked to find the sum of two or more numbers, then you need to add the numbers together.
That's a simple case of evolution, survival of the fittest, natural selection, etc. The ways that were tried and didn't work never lasted long enough to become traditional.
You multiply them.You multiply them.You multiply them.You multiply them.
1. Find out which numbers multiply together to reach the target number, then find out which numbers multiply together to make the numbers that multiply together to reach the target number.
if your numbers arent whole numbers then multiply them out until they are whole numbers that are easier to work with.
You multiply two (or more) numbers together.
you work left to right
There are no two real numbers that do, but two complex numbers do: (3.5 + i 3.5 √23) and (3.5 - i 3.5 √23) If you want them to add to 7 and multiply to -294, then the two real numbers -14 and 21 work. Or if you want them to add to -7 and multiply to -294, then the two real numbers 14 and -21 work. To add to -7 and multiply to 294, the following two complex numbers work: (-3.5 + i 3.5 √23) and (-3.5 - i 3.5 √23)
As a product of its prime numbers: 3*7*11 = 231
Turn them into a fraction and then multiply it by 100
Multiply prime numbers or prime factors to find their product.
To multiply 14 by 16, you would first multiply the two numbers without considering the place value. So the result is 224.
If you are wanting to add odd numbers to get 399, it won't work. If you are wanting to multiply to get 399, it is 19 x 21.
