If a + b = a/b = a*b, then find a - b.
I think a and b are both 0. So, a - b = 0 - 0 = 0 !!!
no, but anythign divided by 0 is undefined.
Two equations two unknowns
a+b = a/b
a*b = a/b or a = a (1/b^2)
1 = 1/b^2 b= 1 or -1
a + 1 = a /1
a+1 = a no answer for when b = 1
a-1 = a /-1
a-1 = -a
2a = 1 a = 1/2 b = -1 then a- b = 1/2 - -1 = 1 1/2
