# Video Series: How to Solve Number Problems Mentally

Last year, I have written a tutorial on **How to Solve Number Problems Mentally**. This article has been turned into a math tutorial video in Youtube under the **Sipnayan** channel. Sipnayan is a Youtube Channel which contains math tutorial videos in Tagalog.

Embedded below are the three videos in the series.

Part 1 solves the following problem:

*One number is 3 more than the other. Their sum is 45. What are the numbers?*

Part 2 solves the following problem:

*The sum of two numbers is 53. One number is 7 less than the other. What are the numbers?*

Part 3 solves the following problem:

*One number is twice the other number. Their sum is 45. What are the numbers?*
