Let x = 1st number and y = 2nd number
x + y = 1 (they add to 1)
xy = 1/2 ( multiply to one half)
rearrange top equation to y = (1 - x) and substitute this into the 2nd
x(1-x) = 1/2 I don't like to work with fractions so multiply by 2 and use the distributive property
2x - 2x2 = 1 rearrange into standard form for a quadratic
2x2 - 2x + 1 = 0
This will not factor using integers. Use the quadratic formula to solve it.
x = (2 + (sq root)(4 - 8))/4 and x = (2 - (sq root)(4 - 8))/4
x = (2 + (sq root)(-4))/4 and x = (2 - (sq root)(-4))/4
Simplify
x = (1 + i)/2 and x = (1 - i)/2

What two numbers do you add to get 0 and multiply to get 80?
80
What two numbers multiply to get seven and add to get eight?
One and seven.
When two numbers multiply the result is increases but when you mutiply .5 and.5 the answer get decreases that is .25 how?
The number .5 means half. So, if you take half of something, that is less than the entire thing, right? And half of half is a quarter. Multiplication only makes numbers larger when you multiply numbers that are greater than one. If you multiply by one the number doesn't change. If you multiply by less than one, you make the number smaller.
What two numbers can you multiply to get negative twelve and add to negative one?
negative 3 and positive 4
How can you change four and one half into an improper fraction?
You multiply two halves, the equivalent of four, by four to get a product of 8 halves. Then add the "extra" half from the original "four and one half" to get nine halves.
