VocabularyDay 1 What is an integer? An integer is a whole number that can be written as a positive whole number, zero, or a negative whole number. The numbers..., -4, -3, -2, -1, 0, 1, 2, 3, 4,... consisting of the negative whole numbers, zero, and the positive whole numbers are called integers. -3 and 31 are both examples of integers. They contain no decimals or fractional components.
VocabularyDay 1 Which of the following is a coordinate? a.a and b b.3 and 5 c.-2.2 d.(5, -20.5)
VocabularyDay 1 What is a coordinate? A coordinate is a pair of values that represent a point on a coordinate plane, also known as an ordered pair, (x,y). The coordinate plane is also known as the Cartesian Coordinate System. It is made up of a horizontal and a vertical number line that intersect at right angles, called the x-axis and y-axis respectively.
VocabularyDay 1 What is absolute value? Absolute value is the distance of a number from zero on the number line. It is written as |n|, where n is a real number. For example, |-4| = 4 or |x| = x and |-x| = x
VocabularyDay 1 Write the absolute value of -23.75?
VocabularyDay 1 The phrase less than is a form of inequality where the real number prior to the phrase or symbol is smaller than the real number that follows the phrase or symbol. For example, 6 < 3 means six is less than three and y < x means y is less than x
VocabularyDay 1 Which of the following is correct? a.7 > 76 b.8 < 9 c.26 < -26 d.-2.32 > 1.4309
VocabularyDay 1 An irrational number is a real number that cannot be written as a fraction, and as a decimal neither repeats nor terminates. For example, π = 3.141592653589793238462643383279... Or – 0.1112131415161718192021... are both irrational numbers

Pre-requisite SkillsDay 2 What is an exponent? An Exponent is a number that appears as a superscript next to a number called a base. It tells you how many times the base needs to be multiplied. The entire number is called a power. For example, 2 4 = 2 · 2 · 2 · 2 = 16; 4 is the exponent a 8 = a · a · a · a · a · a · a · a; 8 is the exponent
Pre-requisite SkillsDay 2 A fraction is made up of two parts: the top number (x) is the a.denominator, divisor b.denominator, dividend c.numerator, divisor d.numerator, dividend
Pre-requisite SkillsDay 2 A fraction is made up of two parts: the bottom number (y) is the a.denominator, divisor b.denominator, dividend c.numerator, divisor d.numerator, dividend
Pre-requisite SkillsDay 2 A fraction is made up of two parts: the numerator (x) and the denominator (y) The bar between the two numbers means divided by, out of, per, or over (i.e. x over y). The top number is the dividend and the bottom number is the divisor.
Pre-requisite SkillsDay 2 When you convert a fraction, you may solve it by dividing the numerator by the denominator. The numerator becomes the dividend and the denominator becomes the divisor of the operation: X ÷ Y = Y Г X In this case, the bar between the two numbers means divided by. The top number is the dividend and the bottom number is the divisor. e.g. = 4 ÷ 5 = 5 Г 4.0 =.8
Pre-requisite SkillsDay 2 A fraction is made up of two parts: The bar between the two numbers means divided by, over, out of, or per. x over y = x out of y = x per y = 7 over 8 = 7 out of 8 = 7 per 8
Pre-requisite SkillsDay 2 A fraction is also used for units of measure: The bar between the two numbers means per. e.g., miles per hour; dollars per week
