calculatorMy father has been in the construction industry most of his adult life, so he’s had years of practicing his math skills. Growing up I was always annoyed that he could do better mental math than me, until it came time for geometry my sophomore year of high school. I realized he was the perfect tutor for learning about triangles and the good ol’ pythagorean theorem. I asked my dad for help one night and he started blabbling on about the angles of roofs and how to calculate them. By the end of the conversation I knew all of the tips and tricks on measuring angles for cutting fascias, but nothing about the pythagorean theorem.
I was thinking about that oh so valuable lesson not too long ago, and it got me thinking about the guys on the job site who aren’t so good at math. What do they do when calculations need to be done and they don’t know how to do it? I got on my “google machine” as my dad calls it, and found there are many apps with calculators specifically made for different types of commercial construction. So, this list of calculator apps for commercial construction is my contribution of help to the construction workers who hate doing math for a job.

Why do math on the job when you have calculators to do it for you?

If you struggle in the math department, don’t be afraid to download these apps to help you out of the job site. Shoot, even if you excel at math, I think it’s worth your time to give them a try. It’s always good to double check a math problem before assuming you got the correct answer the first time; at least that’s what my dad has always told me!
