One
of the most important school subjects is mathematics. Although learning to read
is important, if we do not know how to do simple sums, we will not be able to keep
track of our finances. Besides everyday calculations such as figuring the best
prices per weight in the grocery store/ we need to understand more complex
computation to understand interest rates on our bank accounts and loans for
major purchases. People who earn enough sometimes have financial difficulties because
they do not understand the mathematics behind finances.
Mathematics is also important
in other parts of our lives. For example, we have to measure and calculate
numbers when we cook. We need to know about mathematical functions like fractions
or multiplication when we decrease or increase the amounts depending on the
number of people who are going to be eating. An error in sums could result in a
bad-tasting meal.

The electric streetcar was popular amoung the people
in cities in the US after 1880. when an engineer invented a cable that could
run from wire overhead to a streetcar’s electric engine. because there was this
overhead wire, it wasn’t necessary to have dangerous electric rail running
along the street, and it was a very important feature of the electic streetcar.
During the next 20 or 30 years are so, from 1880 onwards, the electric streetcar was very popular with passangers in big cities all over the USA. It was very efficient, carrying large numbers of passangers without costing very much money for the passengers. However, early in the next century, automobile manufacturers and other business interests made an effort to get rid of all the streetcar in the streets of big cities and replace them with buses and cars.
