Kata

Create two variables of type number. These can be used throughout this kata.

    var a: number = 10;
    var b: number = 5;

Output to the console the addition, subtraction, multiplication, and division of these numbers.

    console.log('a + b = ' + (a + b));
    console.log('a - b = ' + (a - b));
    console.log('a * b = ' + (a * b));
    console.log('a / b = ' + (a / b));

Output to the console the remainder of two divided numbers that yield no remainder and again where a remainder is present.
Tip: The % operator is used.

    console.log('a % b = ' + (a % b));
    console.log('a % b = ' + (a % 6));

Increment and decrement “a” with operators.

    a++;
    console.log('a++ = ' + a);

    a--;
    console.log('a-- = ' + a);

    a--;
    console.log('a-- = ' + a);
