This can be answered using multiplication.

90 X 6 = 540.

A strategy to solving this problem is to ignore the "zero" on the 90 and just multiply 9 X 6 = 54. Then add the zero back on for an answer of 540 calories.

This can be used with any number ending in zero/zeros.

For example:

A candy bar has

**5**0 calories. How many calories in 5 candy bars?5 X 5 = 25. Then add the zero for an answer of 250 calories.

Example:

A candy bar has

**5**00 calories. How many in 5 candy bars?**5**X 5 = 25. Then add the two zeros and the answer is 2,500 calories.
