Do your maths skills need a refresher?


Using the metric system, calculating averages and percentages, and understanding significant figures are integral to our daily work in the engineering and corrosion industry. 

Sometimes, we just need a refresher when it comes to these basic maths skills we were taught in school. This is why our isiFundi team has compiled a free ebook.

Brush up your maths is designed to refresh your understanding of these key concepts you learned all those years ago.
