Here we have first “official” math topic for primary students. These arithmethic videos are full of fun exercises and lessons which help you start students on their journeys towards math mastery. The important subjects are taught by these videos: addition, subtraction, multiplication, and division — but we don’t stop there, then we’ll move into negative numbers, absolute value, decimals, and fractions, too. Learning math should be fun, and we plan on having some with these.
