What do you know about the sums and the product of odd and even numbers?

Even numbers : they can be written 2n
2n1+2n2+....+2nm = 2(n1+n2+....+nm) so it's always an even number
2n1x 2n2x....x2nm = 2(n1+n2+....+nm) which is always an even number
Odd numbers: they canbe written 2n+1
(2n1+1) + (2n2+1) + ....+ (2nm +1) = 2(n1+n2+....+nm) + m which is even if m is even and odd if m is odd, so it depend of the number of terms
(2n1+1) x (2n2+1) x ....x (2nm +1) is always odd cause the last term of the expansion is always +1 and other terms have at least 2 as factor

How do you divide decimals with partial sums method?
To divide decimals the partial sums method requires that numbers are separated into individual portions. The separated numbers are then solved in long division until eliminated.

How many different sums can you make from 5 numbers?

Why was the square root invinted?
To give mathematical completeness; it enables all sums to be solvable, (even if this just means proving that they have no answer) in the same way that inventing "negative numbers", "zero" and "imaginary numbers" enable all maths to be solvable. (Not that all sums have answers).

Do all factor sums have to be even?
No.
How many sums equal 23?
Infinitely many. 12+11, 13+10, 14+9, ... , 22+1, 23+0, 24+(-1), 25+(-2), ... and then you have sums with numbers to one decimal place (dp) such as 11.6+11.4, and so on. Not forgetting numbers to 2 dp, 3, dp, 4, dp, ... , infinitely many dp. But these are only sums of two numbers. There are sums of 3 numbers, 4 numbers, ... infinitely many.
