A brick is a type of block that is used to make walls, roads, and other elements in masonry construction. It is made of clay, sand, lime, or concrete.

| Now we will know about a story. This is the true story of Jagriti School located in Murshidabad (West Bengal). This school is very famous for its great structure.
When its building was being made, there was a plan to make brick patterns on the floor and walls. Jamaal, Kaalu and
Piyaar were the masons for the brick work. They wanted to get
new ideas for the school building. So they took their other friends
to see the old tomb of Murshid Quli Khan (Nawab of Bengal during 1706 to 1725).

brick patterns. These were made by masons long back – about
three hundred years ago.

| Mental Addition
The addition calculated mentally in the head without using paper and pencil is called a mental addition. The student must do a sufficient number of mental additions before proceeding further. Now, let’s learn the mental addition steps by steps.
Rule 1: Always add small numbers to large numbers. For example,
3 + 24 = ?
Here, instead of adding 24 to 3, add 3 to 24.
Therefore, 24 + 3 = 24 + 1 + 1 + 1 = 27
While counting mentally, we go to count three numbers ahead.
Rule 2: If the given numbers are in multiples of 10, then digits at ten’s place are added together and a zero is placed at one’s place in the result. For example,
30 + 50 = ?
Here, digits at ten’s place are 3 and 5.
Therefore, 5 + 3 = 8
Place a zero at one’s place.
Therefore, 50 + 30 = 80
Rule 3: Split big numbers into tens and units, add the units and tens separately and in the last add the Units on the Tens. For example,
47 + 33 = ?
40 + 7 + 30 + 3 =
70 + 10 = 80
Rule 4: When a number is close to the ten, lend from another number to complete the ten. For example,
48 + 33 = ?
50 + 31 =
80 + 1 = 81
