Each equation follows a consistent pattern: add opposite numbers from the circle and then multiply the results. Let's break down each equation.

1. *First Equation:*
 - Step 1: Add opposite numbers:
     - (1 + 4 = 5)
     - (5 + 3 = 8)
   - Step 2: Multiply the sums from Step 1:
     - (5*8 = 40)
   
   Therefore, the result of the first equation is 40.

2. *Second Equation:*

- Step 1: Add opposite numbers:
     - (3 + 3 = 6)
     - (2 + 6 = 8)
   - Step 2: Multiply the sums from Step 1:
     - (6 * 8 = 48)
   
   Therefore, the result of the second equation is 48.

3. *Third Equation:*

 - Step 1: Add opposite numbers:
     - (5 + 1 = 6)
     - (7 + 2 = 9)
   - Step 2: Multiply the sums from Step 1:
     - (6 *= 54)
   
   Therefore, the result of the third equation is 54.

4. *Fourth Equation:*

   Given numbers: 8, 3, 7, 9
   - Step 1: Add opposite numbers:
     - (8 + 3 = 11)
     - \7 + 9 = 16)
   - Step 2: Multiply the sums from Step 1:
     - \(11 * 16 = 176)
   
   Therefore, the result of the fourth equation is 176.
