Diagnostic Test 2016 Level 1
The members of team starfax learned math in an unconventional way such
that they were unable to use calculators. Instead of addition,
subtraction, multiplication, and division, with the numbers ~a~ and ~b~,
the equation ~a\ \$\ b~ equals ~a^2 - b^2~, the
equation ~a\ @\ b~ equals ~(b \times a) / (2a - 3)~, and the equation ~a\ \#\ b~ equals ~(a \times b) (b - 14)~. Due to this being so hard without
calculators, the students requested you to make a program for them.
Given the integers ~a~ and ~b~ ~(-1\,000 \le a \le b \le 1\,000)~, and
an operand ~o~ (
#), calculate the answer to the provided
question. Output the string
The equation [a] [o] [b] is equal to [answer].
The answer will always be an integer after calculations.
Sample Input 1
3 $ 7
Sample Output 1

Sample Input 2
4 # 0
Sample Output 2
The equation 4 # 0 is equal to 0.
