To simplify a fraction to lowest terms, we use the following important principle. Therefore, the number 1 is said to be the multiplicative identity also called the identity element of multi- plication. The value of 7 r, for example, can be approximated as 77 ~ 3. This clear, accessible treatment of mathematics features a building-block approach toward problem solving and realistic, diverse applications. Write a fraction that simplifies to Answers may vary.

Then add this value to the numerator of the fraction, and write the result over the denominator. Determine the difference in elevation, in meters, between the highest mountain in the world and the deepest ocean trench. Then apply the commutative property of addition.

The problem solving strategy, highlighted by A Mathematics Blueprint for Problem Solving, helps students determine where to begin the problem-solving process, as well as how to plan subsequent problem-solving steps. Step 2 Evaluate expressions involving exponents, radicals, and absolute values. Along the way, we will need the skill of recognizing perfect squares and perfect cubes.

NextOn the same day in Springfield, Missouri, it was a pleasant summer temperature of 75°F. Notice that the same result can be obtained by dividing out the greatest common factor from the numerator and denominator. Attend every class, and be on time. The difference of z and the product of x and y Expanding Your Skills For Exercises 107-110, use the order of operations to simplify each expression. Do you keep an organized noteboo with your group members to help them keep their materials organized? Addition of Real Numbers When adding large numbers or numbers that involve fractions or decimals, count- ing units on the number line can be cumbersome.
