INTRODUCTION
If we did not know how to measure, where would we be? Throughout each day, we make various
measurements. For example, we squeeze out the right amount of toothpaste onto the toothbrush.
When we go grocery shopping, we pay according to weight or size of the products we buy. We
measure time with our wristwatches and clocks.
