var a = read("First number: ", Number).int
var b = read("Second number: ", Number).int

%w'+ - * // % ** ^ | & << >>'.each { |op|
    "#{a} #{op} #{b} = #{a.$op(b)}".say
}

Output:

First number: 1234
Second number: 7
1234 + 7 = 1241
1234 - 7 = 1227
1234 * 7 = 8638
1234 // 7 = 176
1234 % 7 = 2
1234 ** 7 = 4357186184021382204544
1234 ^ 7 = 1237
1234 | 7 = 1239
1234 & 7 = 2
1234 << 7 = 157952
1234 >> 7 = 9
