In elementary school, we have learned to use alphanumeric characters as well as some simple equations of knowledge. However, from a practical point of view, many students still prefer to use arithmetic to solve practical problems, often neglecting the quickness of solving problems with equations. So, as a pupil in the calculation, how to adjust ideas, to seize the same amount of relations, to solve the problem with the equation? Here to teach you a few simple and easy to learn: First, to seize the equivalent equation column equation such as: small Swan washing machine according to the sales price of 960 yuan profit, if the sale of 80% of the price, the business is a loss of 832 yuan.
