1) Which one of the following responses is correct?

8 * 5 * 27 * 3 * 16

(1) x, =, -, + (2) -, =, x, +

(3) x, =, +, - (4) +, -, =, x

2) What should be the correct signs of the equation to arrive at the given answer?

17 * 3 * 6 = 45

(1) x, =, -     (2) -, x, =

(3) =, x, -     (4) x, =, +

3) The  symbols for addition (+), subtraction (-), multiplication (x) and division (÷) will have to be inserted in the blank * in order to get answer 3 as shown in the equation:


20   *     5     *   8   *     2     *    17 = 3

Find out which set below is correct.

(1) - + ÷ x    (2) + -  x ÷

(3) x - ÷ +    (4) ÷ + x –

4) Substitute the correct mathematical symbols in place of * in the following equation:

7 * 7 * 2 * 1 = 12

(1) x - ÷       (2) + - x

(3) x - +       (4) + x –

5) Select the correct combination of mathematical signs to replace  * signs so as to balance the equation.

8 * 8 * 1 * 11 * 11

(1) + = ÷ -   (2) x + = ÷

(3) ÷ x + =   (4) - + = ÷

6) Select the correct combination of mathematical signs to replace signs and to balance the given equation.

16 * 4 * 64 * 4

(1) x, <, ÷    (2) x, >, ÷

(3) ÷, >, x    (4) x, >, +

7) Find the correct group of signs to solve the equation.

24 * 16 * 8 * 32

(1) + - =       (2) ÷ - =

(3) - + =       (4) x ÷ =

8) Select the correct combination of mathematical signs to replace * signs and to balance the following equation:

5 * 9 * 3 * 6 * 8

(1) x + = x    (2) x - = x

(3) + ÷ - =   (4) – x ÷ =

9) Select the correct combination of mathematical signs to replace * signs and to balance the given equation:

13 * 12 * 5 * 4

(1) = - +       (2) = + -

(3) + - =       (4) - = +

10) Select the correct combination of mathematical signs to replace * signs and to balance the following equation:

(√121 * 9) * 5 * 4 * 1

(1) - + x =    (2) + ÷ x=

(3) = + x ÷   (4) – x + =
