Set A Write an algebraic expression for each word phrase. 1. take 2 from a number 2. 5 increased by a number 3. 20 is reduced by a number

Translate each algebraic expression into words 4. n-25 5. 17=a 6. 100-c 7. k+12 8. m+n

Evaluate each expression for a=12. Then write 9. a+1 _a-1 10. 100+a _a+100 11. a-5___18-a

Set B Estimate. Tell which method you used. 1. 686+231 2. 346-188 3. 706+197 4. 4,673-3,927 ​5. 9,706+3,048 6. 92,545-36,789

Set C Add or Subtract. Tell which method you used. 1. 342,617 + 629,313 2. 580,604 - 450,000 3. 628,589 + 223,000 4. 781,130 - 674,086 5. 4,453,299 + 3,958,214 6. 6,624,120 - 5,921,532

Set E Use mental math to solve the equations. 1. 4 + z =10 2. 14 - g = 8 3. 5 + p = 12 4. d - 17 = 50 5. 61 + w = 72 6. r - $14 = $35 7. 23 - b = 19 8. n + $9 = $20
