Mathematics is one of the subjects which you can spend hours calculating, studying and deriving equations and you might not end up wiser. Mathematical problems can prove to be tough when you have time constraint. And if you cannot solve the problem after a particular iteration, you are lost. However, there are some techniques for studying and solving mathematical equations that you can apply regardless of your level. Keep your basics clear Do not try to memorize the process. Memorizing mathematical iterations is counter-productive. Thus before beginning to tackle any bigger mathematical equations, get your basics cleared. Clear knowledge of basics help you in understanding how you should approach the problems. It is important to understand that mathematics is a sequential subject so it is important to have a firm understanding of key concepts before you can move on to work on more complex solutions which are based on understanding the basics. Consistent practice It can be very hard to study mathematics properly by just reading and listening. You will always miss out on some important steps to simplify mathematical equations if you have only read the solution of solving the mathematical equation and have not practiced it enough. Each problem has its own characteristics, hence, the more you practice answering mathematical problems, the better.

The Aztecs dealt with more numbers than we do. They had symbols for denoting numerical concepts. When it came to measuring land for levying the property tax or tribute, these medieval Mesoamericans, or the Aztecs used arrows, hearts, hands and other units to represent fractions, say the new study of science. To denote half the Aztec basic unit of measure, known by Aztec experts as tlalquahuitl or land rods, the surveyors used an arrow symbol. So for a field that measured 20 land rods by 10 land rods plus an arrow (or 20 multiplied by 10.5), the correct area was 210. Units such as arrow, heart, hand, bone and arm cannot be subdivided further, standing alone as essentially extra numbers. It is speculated that an arrow is the measure of the length from the shoulder to the hand (like an archer with a taut bow), a heart is a measure of the length from that organ to the tip of the hand and a hand as the measure from outstretched hand to outstretched hand. A set of at least five formulas emerged showing how the Aztec surveyors determined the areas of irregular shapes. In some cases, the Aztecs averaged opposite sides and then multiplied.
