simple algebra 2 1/2 + (-3 1/4)?

2 1/2 + (-3 1/4)
= 2 1/2 - 3 1/4
= 2 2/4 - 3 1/4
= (2 - 3) + (2/4 - 1/4)
= -1 + 1/4
= -4/4 + 1/4
= -3/4

2 1/2 + (-3 1/4) = 5/2 - 13/4 = 10/4 - 13/4 = -3/4
Yes! -3/4 is correct.

In Gianlino's answer, the thoughts of u could nicely be made to offer all the rational solutions! permit n be an integer and set u = a million+a million/n. this delivers x = u^(a million/(u-a million)) = (a million+a million/n)^n and y = (a million+a million/n)^(n+a million). word that x < e < y. this could nicely be a o.k.-prevalent effect.

Method 1
2 + 1/2 - 3 - 1/4
- 1 + 1/4
- 3/4

Method 2
5/2 - 13/4
10/4 - 13/4
- 3/4

Yep, the answer's -3/4.

Yep Big D is right it's -3/4

-3/4
