Description

We can also subtract one number from another. JavaScript uses the - symbol for subtraction.

Example

myVar = 12 - 6; // assigned 6

Instructions

Change the 0 so the difference is 12.

Tests

tests:
  - text: Make the variable <code>difference</code> equal 12.
    testString: assert(difference === 12);
  - text: Only subtract one number from 45.
    testString: assert(/var\s*difference\s*=\s*45\s*-\s*[0-9]*;(?!\s*[a-zA-Z0-9]+)/.test(code));

Challenge Seed

var difference = 45 - 0;

After Test

(function(z){return 'difference = '+z;})(difference);

Solution

var difference = 45 - 33;
