Tick (✓) only the even numbers 11. • 58 (✓) • 12 (✓) • 59 • 93 12. • 75 • 82 (✓) • 60 (✓) • 80 (✓) 13. • 25 • 43 • 60 (✓) • 60 (✓) 14. • 83 • 59 • 60 (✓) • 60 (✓)

Tick (✓) only the odd number 15. • 16 • 17 (✓) • 15 (✓) 16. • 14 • 28 • 18

  1. Step 1: Subtract 13 from 28.

    28−13=1528 - 13 = \boxed{15}

  2. Step 1: Add 44 and 33.

    44+33=7744 + 33 = \boxed{77}

  3. Step 1: Break down the numbers into hundreds, tens, and ones.

    531→500+30+1531 \to 500 + 30 + 1 242→200+40+2242 \to 200 + 40 + 2

  1. Add the corresponding place values.

    $$
(500 + 200) + (30 + 40) + (1 + 2) = 700 + 70 + 3 = \boxed{773}
$$

    20. Step 1: Break down the numbers into hundreds, tens, and ones. 362→300+60+2 362 \to 300 + 60 + 2 242→200+40+2 242 \to 200 + 40 + 2

  2. Add the corresponding place values.

    $$
(300 + 200) + (60 + 40) + (2 + 2) = 500 + 100 + 4 = \boxed{604}
$$

    THEORY SECTION B

    1. a) Give 10 examples of odd numbers: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19

      b) Give 10 examples of even numbers:
      2, 4, 6, 8, 10, 12, 14, 16, 18, 20

    2. a) Step 1: Divide 20 by 2.

      20÷2=1020 \div 2 = \boxed{10}

      b) Step 1: Divide 16 by 2.

      16÷2=816 \div 2 = \boxed{8}

      c) Step 1: Divide 20 by 4.

      20÷4=520 \div 4 = \boxed{5}

    3. Step 1: Multiply 13 by 3.

      13×3=3913 \times 3 = \boxed{39}

    4. Step 1: Multiply 23 by 2.

      23×2=4623 \times 2 = \boxed{46}
