Instructions- Read It carefully**(I got a null result)**

1.

We’re going to do a mathematical “magic” trick. Create a variable, `\$my_num` and assign as its value any number.

Next, create a second variable, `\$answer` and assign `\$my_num` as its value.

2.

Use the addition assignment operator to add 2 to `\$answer` .

Hint

The point here is to practice using the handy mathematical assignment operators:

\$example += 9;

3.

Use the multiplication assignment operator to multiply `\$answer` by 2.

4.

Use the subtraction assignment operator to subtract 2 from `\$answer` .

5.

Use the division assignment operator to divide `\$answer` by 2.

6.

Almost there. Use the subtraction assignment operator to subtract your original number ( `\$my_num` ) from `\$answer` . Finally, use `echo` to print `\$answer` to the terminal.

If everything went as it should, `\$answer` should be 1. No matter what your original number was! Don’t belive us? Go ahead try it with a different number for the value of `\$my_num` .
