useful for simplifying algebraic expression because a lot of thing we do in life are equations. We use a lot of mathematical terms in the real world. Lastly I will show every step I took to simplify and identify each property of real numbers. The properties of algebra are important to know and understand. “Algebra is useful because it can be used to solve problems. Since problems are often communicated verbally‚ we must be able to translate verbal expressions into algebraic expressions and translate

Homework Sheet - Basic Algebra 1. John and Sarah are simplifying this expression. 3a + 8b + 7a – 6b John says the answer is 2a + 2b and Sarah says the answer is 10a + 14b. What is the correct answer? Sarah 2. Simplify these expressions. a) 4d + 6e – 2d – 3e = 2d-3e b) 12g – 3h – 8g + h = 4g-4h c) k + 2k + 3k – m – 2m – 3m = 6k-3m d) 7c + 4d – 10c + 5d = -3c+9d 3. Multiply out these brackets. a) 3(2a + 7) = 6a+21 b) 5(3x – 2y) = 15x-10 c) 2(4g2 – 3g) = 8g2-6

rule and give an example. The main rule for a negative exponent is to always first make it into a positive before you start simplifying. For example y^-4+7=x The first thing you would do is write it as this 1/y^4+7=x Once this is completed you can then simplify. 154. How do you know if an exponential expression is simplified? You can tell if an exponential expression is simplified when it brought down to the lowest possible simplification. For example 6y^3+y^3=x These are like terms and

of economics? What role does the “division of labour” play in defining this subject matter? Quoting Michael Yates‚ “The subject matter of economics is the production and distribution of output…” (Yates‚ 2003). So what does this say to me? Simplifying‚ this says to me that Economics is a way of explaining the world. With studies dating as far back as Aristotle’s interest in the various forms of state‚ how can one ever fully understand the complexities of economic thought and how could one definition

√7‚ Π. These numbers cannot be written as a fraction so they are irrational. Surds A surd is any number that looks like this √21‚ √15‚ √17. A surd is a root that cannot be written exactly as a decimal or a fraction. They are irrational. Simplifying Surds A surd can be simplified by rewriting the number inside the root as a product of two other numbers‚ one of which is its largest square factor. The square root of this factor is then written outside of the root sign. Rules of Surds Surds

Book #1‚ Unit #1 Number Simplifying Fractions To change a fraction or a decimal into a percentage‚ multiply it by 100. To change a percentage into a fraction‚ rewrite % as division by 100. To write a fraction as a decimal‚ divide the top number by the number. To change 1/8 into a decimal: divide 1 by 8. 0.125 To change 7/20 into a percentage: multiply by 100. 7/20 x 100 = 35% To simplify 15/1.2: multiply top and bottom by 10. 150/12 = 25/2 = 12.5 Directed Numbers 3 + (-4) = 3 - 4 = - 1 3 - (-4) =
