SHSAT STUDYWhole Numbers - correct answer non-negative numbers including zero Integers - correct answer positive or negative whole numbers including zero Prime Numbers - correct answer positive integers that can only be divided by one and itself Factor - correct answer a factor is a number that divides evenly into a given number-that is, has no remainder Greatest Common Factor - correct answer the greatest common factor the divides two numbers without a remainder. 1. List the prime factors of each number. 2. Multiply together only the factors that both numbers have in common to find GCF 3. If the two numbers do not share any common prime factors, their greatest common factor is 1 Multiple - correct answer An integer multiplied by another integer results in a multiple of each integer; an integer is a multiple of another integer if the remainder is 0 when you divide the larger integer (in absolute value) by the smaller integer. Least Common Multiple - correct answer the least common multiple of two (or more) integers is the smallest positive integer that is a multiple of each of those integers. To find the LCM of a set of numbers: 1. Factor out each number and express it as a product of prime numbers. 2. Find the LCM by multiplying together the highest power of each prime factor that happens in any of the numbers. Convert Fractions to Decimals - correct answer divide the numerator by the denominator Convert Decimals to Fractions - correct answer pu the decimal over the place and reduce. The decimal is followed by the tenths, hundredths, thousandths... Multiplying Decimals - correct answer Multiply as if hey were whole numbers (line up the numbers to the right; do not line up decimal points .) After multiplied throughly move the decimal points to the left . Dividing Decimals - correct answer If the divisor (the number you're dividing by) isn't a whole number, mov the decimal point right to make it a whole number; then move the decimal in the dividend (the number being divided) to the right the same number of places then divide as usually. Rounding and Place Value - correct answer to round to any place value, look at the preceding places value. If it is 5 or more, round up by one. If the preceding lace values digit is less than 5, leave the originally digit alone. Order of Operations - correct answer use PEMDAS P= Parenthesis E= Exponents M&D= Multiplication & division (left to right) A&S= Addition & Subtraction (left to right) What - correct answer some variable (x) Is - correct answer = Sum - correct answer + Subtract - correct answer - Difference - correct answer - Of - correct answer * or x
