- 3. Property - a number in front of a group of terms will multiply all terms in the grouping individually. (a(b + c) = ab + ac)
- 6. Algorithm: ________ - Algorithm for solving multiplication. Expand each factor into hundreds, tens, ones, etc. and then multiply and add.
- 7. Algorithm: ________ - Algorithm for solving addition. Add each place value separately and then find the total.
- 9. Algorithm: _______ – Algorithm for solving division. Separate the problem into columns and work with each place value separately.
- 10. Algorithm: ______ - Algorithm for solving division. First estimate the answer using base-10 numbers and then keep estimating until the remainder is less than the dividend.
- 11. Property - An operation is commutative if changing the order of terms does not change the outcome. (A + b = b + a)
- 12. Algorithm: _______ - Algorithm for solving addition. Align numbers based on place value and then add each column.
- 14. - indicate repeated multiplication and are written above and after the number in question in the form: x^n where n represents the number of times multiplication is repeated. (3^2=3∙3)
- 15. Algorithm: _________ - Algorithm for solving addition. Add a number to one addend to make a number ending in zero and subtract the same amount from the other addend.
- 17. - a specific set of steps that allows the user to reach the correct answer every time.
- 18. - The number under the radical symbol. (y is the radicand of √y
- 19. - an expression with one or more terms; terms may include exponents that may only be whole numbers and may not include division by a variable. (4x−5)
- 20. Algorithm: ________ - Algorithm for solving subtraction. Add or subtract the same amount from both numerals and then subtract.
- 21. Algorithm: _________ - Algorithm for solving multiplication. Using the concept that multiplication is repeated addition, students use base-10 numbers to multiply and add.
Down
- 1. Algorithm: ______ - Algorithm for solving subtraction. Subtract each place value separately beginning with the largest and working to the smallest.
- 2. Property - An operation is associative if regrouping the terms does not change the outcome. (a + b) + c = a + (b + c)
- 4. Algorithm: _________ - Algorithm for solving subtraction. Align numbers vertically based on place value and then ensure all top numbers are equal or larger than the bottom numbers.
- 5. - A fraction with a polynomial in the numerator, denominator, or both. (2x + 6)/7
- 8. Algorithm: _______ - Algorithm for solving subtraction. Start with the number that is being subtracted and count up to the original amount with each step looking for the next base-10 number.
- 13. Algorithm: _______ - Algorithm for solving multiplication. Draw a lattice with diagonals in each box Write one factor across the top and one along the right side (58 x 213) Multiply each number and write the answer in the box with the tens digit on top (Top left box is 5 x 2 = 10) Add the diagonals beginning in the bottom right corner (4) If the sum is greater than 10, move the 1 to the next diagonal The answer will be along the left side and bottom (red arrow).
- 16. - The process of eliminating a radicals or imaginary number from the denominator of an algebraic fraction. c/√a×√a/√a=(c√a)/√(a^(2 ) )=(c√a)/a
