    Solve all option one by one.
    Change the symbol in given question.
    From option (D),
    4 A 3 M 2 L 4 D 2 M 6
    4 + 3 X 2 < 4 ÷ 2 x 6
    Apply the BODMAS Rule.

    Correct Option: D

    Solve all option one by one.
    Change the symbol in given question.
    From option (D),
    4 A 3 M 2 L 4 D 2 M 6
    4 + 3 X 2 < 4 ÷ 2 x 6
    Apply the BODMAS Rule.
    10 < 12


  1. If the mathematical signs interchange from - to +, + to ÷. x to - and ÷ to x, then find out the correct answer of the given equation
    6 ÷ 8 + 2 x 5 - 8 = ?
    1. 27
    2. 18
    3. 32
    4. 28

    Interchange the symbol as per given in question.
    6 ÷ 8 + 2 x 5 - 8
    After changing the sign
    = 6 x 8 ÷ 2 - 5 + 8
    Apply the BODMAS Rule.

    Correct Option: A

    Interchange the symbol as per given in question.
    6 ÷ 8 + 2 x 5 - 8
    After changing the sign
    = 6 x 8 ÷ 2 - 5 + 8
    Apply the BODMAS Rule.
    = 6 x 4 - 5 + 8
    = 24 - 5 + 8 = 32 - 5 = 27

    Solve all option one by one.
    Choosing the option D,
    3 δ 6 • 2 γ 8 η 4 ω 5
    Then, after placing of signs in given question,
    3 + 6 - 2 x 8 ÷ 4 = 5
    Apply the BODMAS Rule.

    Correct Option: D

    Given question is,
    3 δ 6 • 2 γ 8 η 4 ω 5
    Then, after placing of signs in given question,
    3 + 6 - 2 x 8 ÷ 4 = 5
    Apply the BODMAS Rule.
    9 - 2 x 2 = 5
    5 = 5


  1. Select the correct combination of mathematical signs to replace '*' signs and to balance the given equation.
    24 * 34 * 2 * 5 * 12
    1. + ÷ x =
    2. = ÷ + -
    3. = ÷ - +
    4. + ÷ = x

    Solve by using all option one by one.
    Use BODMAS rule to solve the equation.

    Correct Option: C

    Solve by using all option one by one.
    Choosing option (C) and change the sign.
    24 = 34 ÷ 2 - 5 + 12
    Use BODMAS rule to solve the equation.
    24 = 17 - 5 + 12
    24 = 29 - 5
    24 = 24



  1. Find the correct group of signs to solve the equation.
    24 * 16 * 8 * 32
    1. ÷ - =
    2. - + =
    3. x ÷ =
    4. + - =

    Solve by using all option one by one.
    Given equation is
    24 * 16 * 8 * 32
    Taking the sign of option (D),
    ⇒ 24 + 16 - 8 = 32
    Apply the BODMAS Rule in equation.

    Correct Option: D

    Solve by using all option one by one.
    Given equation is
    24 * 16 * 8 * 32
    Taking the sign of option (D),
    ⇒ 24 + 16 - 8 = 32
    Apply the BODMAS Rule in equation.
    ⇒ 40 - 8 = 32 ⇒ 32 = 32
    Hence, correct group of sign is option (b).
