1. Solve Exercise 1 Page 8 Math Grade 3

Exercise: Mental Calculation

Answers: 9 + 5 = 14, 13 - 4 = 9, 8 + 2 = 10, 10 - 3 = 7. 19 + 5 = 24, 23 - 4 = 19, 38 + 2 = 40, 50 - 3 = 47. 29 + 5 = 34, 83 - 4 = 79, 98 + 2 = 100, 100 - 3 = 97.

Guide: For addition: Break numbers into tens and add mentally. For example, 18 + 6 = 18 + 2 + 4 = 20 + 4 = 24. For subtraction: Subtract to get a multiple of ten then continue with the remaining number. For example, 43 - 5 = 43 - 3 - 2 = 40 - 2 = 38.

Answers: 9 + 5 = 14, 13 - 4 = 9, 8 + 2 = 10, 10 - 3 = 7. 19 + 5 = 24, 23 - 4 = 19, 38 + 2 = 40, 50 - 3 = 47. 29 + 5 = 34, 83 - 4 = 79, 98 + 2 = 100, 100 - 3 = 97.

2. Solution to Exercise 2 Page 8 Math Grade 3

Exercise: Set up and then solve:
49 + 25 = 74, 63 - 58 = 5, 37 + 63 = 100.
637 + 151 = 788, 524 - 219 = 305, 362 + 418 = 780.

Guide: Set up the calculations in a vertical column, aligning rows with each other. Perform the calculations from right to left.

Answers: 49 + 25 = 74, 63 - 58 = 5, 37 + 63 = 100. 637 + 151 = 788, 524 - 219 = 305, 362 + 418 = 780.

3. Solution to Exercise 3 Page 8 Math Grade 3

Exercise: A book has 148 pages. Minh has read 75 pages. How many pages of the book has Minh not read?
