In Chaldean numerology, some analysts of sports events use interchangeable numbers. Personally, I do not engage in sports predictions. Nevertheless, interchangeable numbers help me understand the dynamics of relationships between numbers.

This knowledge originates from Persian numerology and was primarily explored by Chaldean numerologists in the first half of the 20th century.

The interchangeable numbers are as follows:

• 1, 4, and 8
• 2 and 7
• 3 and 6
• 5 and 9
• Numbers from the group of 1 & 4 and numbers from the group of 2 & 7 are partially interchangeable
• The numbers 3 and 5 are also partially interchangeable
