NCCER Core Module 2 Exam Questions and Answers 100% Correct Graded A+ 2026/27
Digit - any numerical symbol from 0 to 9
Place Value - The exact number a digit represents in a whole number, determined by its
place within the whole number or by its positon relative to the decimal point. In the number 124,
the number 2 represents 20 since it is in the tenths position.
Decimal - A part of a number represented by digits to the right of a point, called a decimal
point. For example, in the number 1.25, .25 is the decimal portion of the number. In this case, it
represents 25 percent of the whole number 1.
Difference - The result of subtracting one number from another. For example, in the
problem 8 - 3 is 5. 5 is the difference between the 2 numbers.
Dividend - In a division problem, the number that is divided into another number is called
the divisor.
Equation - A mathematical statement that indicates that the value of two mathematical
expressions, such as 2.2 = 4 and 1.4 =4 are equal. An equation is written using the equal sign in
this manner: 2x2 = 1x4.
Fraction - A portion of a whole number represented by 2 numbers. The upper number of a
fraction is known as the numerator and the bottom number is known as the denominator.
, Negative Number - Numbers less than zero. For example, -1, -2, -2
Positive Number - Numbers greater than zero. For example, 1, 2, 3 are positive numbers.
Product - The answer to a multiplication problem.
Quotient - The result of a division problem.
Remainder - The amount left over in a division problem.
Sum - The resulting total in an addition problem.
Whole Numbers - Complete number units without fractions or decimals
Denominator - The part of the fraction below the dividing line
Equivalent Fractions - Fractions having different numerators and denominators but still
have equal values (like 1/2 and 2/4)
Improper Fractions - A fraction whose numerator is larger than the denominator (lie 8/4)
