However, before you can use the forum, you need to register. If you have registered, you can login and then ask or answer questions. Don’t worry, it’s FREE.

## Video: How to Subtract Integers

This math video is a supplement material How to Subtract Integers.  In this video, I have explained how to convert a subtraction problem into addition problem in order to simplify it. This way, you only have to master addition of integers.

The idea is that all numbers that are of the form $a - b$ can be converted into $a + (-b)$.  Therefore, any subtraction can be converted into an addition problem. Watch the video to understand this strategy.

## Inspiring Comments From You – Thank You!

I have collected several comments from this blog at nakakatuwa at nakakataba ng puso na naappreciate nyo ang civilservicerview.com. These comments inspire me to write more.

Marami pa akong nakalinyang topics na isusulat. Kahit pasado na kayo sa Civil Service Exam, I am encouraging you to read them. Puntahan nyo rin ang Sipnayan.com, maraming tagalog math videos doon kung gusto nyo mag-aral ng math.

Ang pagaaral, lifetime yan. Hindi yan nagtatapos pag-graduate ng college. Pag marami kayong alam, marami kayong matutulungan (believe me, knowledge is really power). Kung single kayo, magagamit nyo yan later sa mga anak ninyo or kung kailangan nyo ng part-time job, pwede kayo magtutor kung alam nyo ang Math at English. Pag bihasa kayo sa Math and English, any exam na i-take ninyo in the future, hindi kayo masyadong mahihirapan.  » Read more
