Each time you calculate the price per unit, weigh produce, figure percentage discounts, and estimate the final price, you're using math in your shopping experience.
While it may be true that some of the more abstract mathematical concepts rarely come into play, the underlying skills developed in high school math classrooms resonate throughout a student's lifetime and often resurface to help solve various real-world or work-related problems--sometimes years down the line.
Fractions, decimals and percentages We use a decimal system to write down numbers. In terms of testing babies, we cannot ask them to tell us what they think.

In this example, assume that you have bought a pack of balloons, the pack is made up of 5 different colours, you count each colour and find that you have: 18 Red.
More advanced forms of this kind of maths are used to find out about the way diseases spread and the effects of global warming. Now you can determine the best route depending on terrain, speed limit, and so on.
