Arithmetic

Arithmetic in Haskell

Haskell supports the standard arithmetic operators:

main :: IO ()
main = do
  print (2 + 3)    -- 5
  print (10 - 4)   -- 6
  print (3 * 7)    -- 21
  print (15 `div` 4)  -- 3  (integer division)
  print (15 `mod` 4)  -- 3  (remainder)
  print (2 ^ 10)   -- 1024

Integer vs Float Division

Use div for integer division (like // in Python). The / operator is for floating-point numbers:

print (7 `div` 2)   -- 3
print (7.0 / 2.0)  -- 3.5

Negative Numbers

Wrap negatives in parentheses when passing to functions:

print (abs (-5))   -- 5
print (negate 3)   -- -3

Your Task

Compute and print:

1. 100 div 7
2. 100 mod 7
3. 2 ^ 8
