Answer 2

Answer:

5

Step-by-step explanation:

Numbers are physically constructed and manipulated in Abacus.

In general practice, we take the help of the abacus formula to do addition and subtraction, especially when there are not enough beads in a column to add on Abacus. It involves using the concept of small friends and big friends for solving basic operations.

Big friend

addition= +5

add 10 less 5

Small friend

subtraction= -5
