Every student have a problem. This is problem solving strategies from Algebra. that is understant the problem , situation, information and what the question is asking. For many problem , drawing a cleary labeled pisture is very helpful. and then the plan: first focus on the objective, than look the given information, and if the information don't unreasonable look at the given information often will find another piece of information can use the answer the information.use the mathematical system of logical relationships between information given and the answers you seek. This involves: use the symbol to the number represented. The most frequently used is x, but it's better to use remember symbols that represent what is in. Translate Englist to math, because because mathematics is a language that is suitable to describe logically.
Read the problem with caution, determine what is known, what is not known and what was asked, represent unknown quantities in terms of a variable , use diagrams where appropriate., find formulas or mathematical relationships between the knowns and the unknowns ,solve the equations for the unknowns. ,check answers to see if they are reasonable.
Example: Find a number such that 5 more than one-half the number is three times the number
| Let x be the unknown number. | |
Translating into math: | 5 + x/2 = 3x |
Solving: (First multiply by 2 to clear the fraction) | 5 + x/2 = 3x 10 + x = 6x 10 = 5x x = 2 |
