Brandon Math Question

25. The following expression has a value of 1.

[-1/2+(-1/2)] / [ -1/2 + (-1/2)]

Use -1/2 four times to write expressions with each of the following values.

a) 0 b) 1/4
c) 1/4 d) 4
e) -3/4 f)-1 1/2

What I did is

a) [-1/2+(-1/2)] / [ -1/2 + (-1/2)] = 0

b) [-1/2) - (-1/2)] + [ -1/2 x (-1/2)] = 1/4

c) [-1/2) x (-1/2)] / [ -1/2 x (-1/2)] = 1/4

d) (-1/2) / (-1/2) / (-1/2) / (-1/2) = 4

e)[ -1/2 + (-1/2)] - [(-1/2) x (-1/2)] = -3/4

f) (-1/2) / (-1/2) / (-1/2) - (-1/2) = -1 1/2

  2. Good job Brandon. I like that you had the answers, but you should have explained to us how you did that. It isn't clear at all how you got your answers. Also, some parts of your post aren't very neat. You might also want to try adding some colour.
