About this unit

The most fundamental branch of math is having a clear idea on number sense and numeration. It consists of understanding place values, adding, subtracting, multiplying, and dividing numbers. We're willing to bet that doing these operations on whole numbers is a piece of cake, but now we'll mix those numbers up with decimals and fraction and exciting concepts like ratios and percentages. So sharpen that pencil and relax in your chair, we're going for a ride!
