NYSTCE Math (246)
place value - (correct Answer) - The value of a digit based on its position within a number
100.001 - (correct Answer) - hundreds, tens, ones, tenths, hundredths, thousandaths
scientific notation- decimal notation - (correct Answer) - Positive exponent means you move decimal to
the right adding more zeroes
Negative exponent decimal moves to the left making number smaller
Dividing with decimals - (correct Answer) - Move the point to the right to make the divisor a whole
number. Move the decimal the same amount of spaces to the right in the dividend
Multiplying Decimals - (correct Answer) - 1. Multiple numbers as if whole numbers.
2. Then count total number of decimal places in the factors and add them (Ex: 2.2 and 2.33 has three
total decimal places)
3. Add the total number of Decimal places to product, counting left to right (Ex: 22*233 = 5126 --> 5.126
final answer)
prime number - (correct Answer) - A whole number that has exactly two factors, 1 and itself.
composite number - (correct Answer) - A number with more than two factors
Divisibility - (correct Answer) - The ability for one number to be divided by another number without a
remainder.
Factors - (correct Answer) - Numbers that are multiplied together to get a product
LCM - (correct Answer) - Least Common Multiple
GCF - (correct Answer) - Greatest Common Factor
Adding and Subtracting Fractions - (correct Answer) - The denomination has to be the same. If it is
different find the lowest common multiple of the denominators. 5/6 - 3/4 =5/6 x 2/2 - 3/4 x 3/3 = 10/12 -
9/12 = 1/12.
multiplying fractions - (correct Answer) - To multiply fractions, multiply the numerators and multiply the
denominators
Dividing Fractions - (correct Answer) - keep change flip.
Number classification - (correct Answer) - REAL NUMBERS
A) Rational (fractions, repeating)
-Integers (-2, even square roots)
-Whole Numbers (0,1,2)
