Alphabet Math Project Liz Perejilo Block D (Day 1) Math 9 A Algebraic equations Equations that have a variable in the question that you need to solve. I learned that in algebraic equations that you can reverse the question to figure out the variable. Ex: 3x + 7 = 16 B BFSD – Brackets, Fractions, Solve, and Divide (Best friends share deserts) Shows the order of solving an equation I learned that this is an easy way to remember how to find the answer quickly. C Chord A line segment on the interior of a circle. A chord has both endpoints on circumference the circle. I learned a chord can be any line anywhere in the interior of a circle as long as it is touching the circumference in two places D Distribute To multipy out the parts of an expression. Distributing is the opposite of factoring. I learned distributing is an easier way to see the question if you are confused Ex: 3(2+7)=3x2+3x7 E Equations A mathematical sentence built from expressions using one or more equal signs (=). Ex: 78 + 3 = 81 F Flip Changing the sign of a number by making it the opposite. I learned that you can flip the sign of the numbers to be sure that the variable is positive. G Greater than When a number is bigger in value than the one it is being compared to I learned that you can only have a number that is bigger in value on the right Ex: 8<9 H Height of a prism A line segment on the interior of a circle. A chord has both endpoints on the circle. I learned that knowing the height of the prism can help you find the surface area because it is connected to all the sides I Isosceles A triangle with two sides that are the same length I learned that isosceles have two sides that are the same and that if you cut them in half, you get a right triangle with 90⁰ J Just add the exponents In the multiplication law of exponents: when the bases are the same, you just add the exponents I learned a short cut with multiplying exponents, when you have two o the same bases, you just add the exponents Ex: 2⁵ x 2³ = 2⁸ K Know your angles Knowing your angles helps you when you have to name the angle or to figure out the degrees of the angle. I learned knowing angles helps you get stuff done faster. Ex: A right angle is 90⁰, if you automatically know it, you don’t have to measure it. L Length The measurement or extent of something from end to end; the greater of two or the greatest of three dimensions of a body. I learned that the length is perpendicular to the height, and that you need the length to find the surface area M Monomial A polynomial with one term I learned that you don’t need more than one variable, number or exponent to make it a polynomial. Ex: 5x³ N Numerator The top part of a fraction I learned that you can divide the denominator by the numerator. Ex: ³/₆ -> 3 is the numerator O Obtuse triangle A triangle in which has an obtuse angle as one of its interior angles Ex: P Power The result of raising a base to an exponent I learned that you can make the number look simpler and making a power is linked to multiplication Ex: 8 is a power to 2 -> 2³ Q Quotient The result of dividing two numbers or two expressions I learned that if you have one quotient and multiply it by 2, you get the original number Ex: 40 divided by 2 = 20, 20 is the quotient R Ratio The result of dividing one number or expression by another. Occasionaly, ratios are a proportion 4:7 (Four to seven). M Mostly they are fractions Ex: 2:3 (Two to three) S Simplify By adding number that are the same or creating zero pairs to shorten the equation. I learned that simplifing a question makes it easier to solve Ex: 3x + 7 = 8x – 7 (3x + 8x = 11x) (+7 -7 = 0) = 11x T Tangent A line tangent to a circle is perpendicular to the radius to the point of tangency. U Expanding using the distributive property Ex: (2x) (3x-1) 2x (3x) + 2x (-1) V Variable A variable is a letter used to replace the unknown number in an equation. I learned how to find the number of the variable Ex: 3 r + 7 = 5 r – 4 W Width the measurement or extent of something from side to side X X axis The X axis is perpindicular to the Y axis, it is used in graphing charts to identify the horizontal line Y Y axis The Y axis is the line in a graphing chart that is vertical Z Zero pairs When you have 2 numbers on each side of the equal sign which cancel each other out. I learned that making zero pairs makes the question easier and shorter.
