Praxis 7813- Counting & Operations- Questions and Answers
1. number line a straight line where each number is equal distance from the next one
2. dividend a number that is divided by another number (divisor) to find the
quotient
3. counting on starting on one number and counting until reaching the second num-
ber; a typical technique is saying the counting numbers out loud while
using fingers to keep track of how many numbers have been used
4. area models using expanded form of a number, each number is multiplied together
and the products are added to find the final answer
5. sum the result of adding two or more numbers (addends); an addition total
6. difference the result of subtracting one number from another
7. rectangular arrays dots or objects that show the end product of 2 numbers; the objects
are arranged so there are an equal number of items in each row and
column
8. remainders the number remaining that cannot be divided as ti is less than the
divisor
9. expanded form/expand- break apart each digit in the number and show the digits true value
ed notation i.e. 4,358--> 4,000+300+50+8
10. quotient the result of dividing two numbers (a division answer)
11. divisor a number that divides another number (dividend) to find the quotient
12. order of operations PEMDAS: the set order in which multi-step equations must be solved:
parenthesis, exponents, multiplication and division (left to right), ad-
dition and subtraction (left to right)
13. product the result of multiplying two or more numbers
1/2
