Now we are starting the lessons of Abacus Level 3.
In Abacus Level 3 we will do 3 digit sums and also do mental math finger practice.
Our 3 digit sums will be in 3 digits and Abacus Mental Math Practice sums will be in 1 digits in [ 6 Rows, 7 Rows, 8 Rows, 9 Rows, 10 Rows ].
Here you are also being given a formula chart of Abacus Level 3 with the help of which you will be able to calculate 3 digit sums easily.
So now let’s start our Abacus Level 3 Book Lesson 1 to 10.
