    β€˜Γ—β€™ means β€˜-’ and β€˜Γ·β€™ means β€˜+’, then choose the correct expression from the following options.
    A 40 - 4 Γ· 6 + 4 Γ— 28 = 12 Correct Answer Incorrect Answer
    B 52 - 13 Γ— 8 + 4 Γ· 20 = 5 Correct Answer Incorrect Answer
    C 8 + 5 Γ· 6 + 4 Γ— 15 = 49 Correct Answer Incorrect Answer
    D 18 + 3 Γ· 10 - 5 Γ— 15 = 30 Correct Answer Incorrect Answer

    Solution

    1) 40 - 4 Γ· 6 + 4 Γ— 28 = 12 40 Γ· 4 + 6 x 4 – 28 = 12 10 + 6 x 4 – 28 = 12 10 + 24 – 28 = 12 10 – 4 = 12 6 β‰  12 2) 52 - 13 Γ— 8 + 4 Γ· 20 = 5 52 Γ· 13 – 8 x 4 + 20 = 5 4 – 8 x 4 + 20 = 5 4 – 32 + 20 = 5 24 – 32 = 5 -8 β‰  3 3) 8 + 5 Γ· 6 + 4 Γ— 15 = 49 8 x 5 + 6 x 4 – 15 = 49 40 + 24 – 15 = 49 64 – 15 = 49 49 = 49 4) 18 + 3 Γ· 10 - 5 Γ— 15 = 30 18 x 3 + 10 Γ· 5 – 15 = 30 18 x 3 + 2 – 15 = 30 54 + 2 – 15 = 30 56 – 15 = 30 41 β‰  30
