Numbers in Everyday Lives
Numbers are important in our lives because of the great power they contain. They can be sorted, added, subtracted, multiplied, and divided. But have we ever thought to use math in everyday lives where there are only taxes to do?
In math class, you learned how to add, subtract, multiply, and divide any number, such as a fraction, a whole number, decimals, and more. You learned geometry, the properties of shapes and three-dimensional figures, different kinds of symmetry, and angles. You learned algebra, learned to replace variables with numbers with problems and dish out formulas to find area of shapes. Do these help in everyday usage?
Math is everywhere, mostly because there is a bunch of things that have numbers in it. Say you bought groceries from your favorite shop. If the tax in the state was 10%, you would need to pay 10% more than usual. If you bought $30.68 off of groceries, you would have to pay $3.07 off of tax. Add this up and you get $33.75, which is 110% of your original price.
It works in banks and coins, too. Say you had 11 quarters, 2 dimes, and 5 pennies. You are going to the bank to exchange coins to dollars. The math would be 2.75 + 0.20 + 0.05, which equals 3. That means you will get $3 from 11 quarters, 2 dimes, and 5 pennies. Math is everywhere now.
Math is one of the most inventive subjects of all time because of the innovative rules made all the time. Math has many adjectives to describe itself: calculations, creative, brain-teasing, and more. Maybe there is the improvement that comes, but math will always mean the same to us always.
