Question

The first line contains integer N size of operations where 1 ≤ N ≤ 50 . Second line contains N-times (operator, variable1 and value1, variable2 and value2)
Output
Output must be in this format -> a + b = 2. HINT: map
Examples
standard input standard output
3
+ a2b3 - x3y1 * y1z5
a+b=5 x-y=2 y*z=5

z 10 b 43
-
u 19 m 32
b + u = 59
z - r = -36
f + b = 35
b * j = 899
z * b = 430
u - m = -13
