**Math Riddles: Missing Number Math Puzzles**

**Logic Puzzle #1**

**Logic Puzzle #2**

**Solution**

**Logic Puzzle #1**

**Answer: 77**

**Explanation**

We will first solve Shape 1 and Shape 2 to understand the logic.

**Shape 1**

=> (7 – 3) x (11 – 2)

=> 4 x 9

=> 36

**Shape 2**

=> (13 - 5) x (9 - 1)

=> 8 x 8

=> 64

Similarly, we shall apply the same logic to solve Shape 3.

**Shape 3**

=> (11 – 4) x (16 – 5)

=> 7 x 11

=> 77

**Logic Puzzle #2**

**Answer: 4**

**Explanation**

We will start by solving Circle 1 and Circle 3 to figure out the logic.

**Circle 1**

If you notice the inner circle highlighted in yellow, you will notice that this circle consists of numbers from the number series 1 to 9.

**Circle 3**

Moving on to the outer circle highlighted in yellow, you will notice that this circle too consists of numbers from the number series 1 to 9.

Similarly, we shall apply the same logic to find out the missing number in the place of the question mark.

**Circle 2**

Coming to the circle in the middle circle highlighted in yellow. We shall follow the same logic as for both circles we discussed above. So, by that logic, this circle should also consist of all numbers from the number series 1 to 9.

Upon looking carefully, we notice all numbers are present in the circle except for number 4. Hence, as per the logic, the missing number in the number series in this circle is 4.
