130 There are 3 516 mangos trees and 2 322 guava trees in an orchard. What is the total number of trees?

To find the total number of trees, we add them.

Number of mango trees = 3516

Number of guava trees = 2322

Total number of trees: 3516 + 2322 = 5838

Step 1

Add ones: 6 ones + 2 ones = 8 ones

Step 2

Add tens: 1 tens+ 2 tens = 3 tens

Step 3

Add hundreds: 5 hundreds + 2 hundreds = 8 hundreds

Step 4

Add thousands: 3 thousands + 2 thousands = 5 thousands

So, total number of trees is 5 838

# Addition of numbers upto 4-digit with carrying

Areeba has Rs 6 388 while Affan has Rs 2 424. What is the total amount they have altogether?

Areeba has amount = 6388

Affan has amount = 2424

Total amount = 6388 + 2424 = 8812

Step 1

Add ones: 8 ones + 4 ones = 12 ones = 1 ten and 2 ones Write 2 at ones column and carry 1 ten to the tens column.

Step 2

Now, add tens: 8 tens + 2 tens + 1 tens = 11 tens = 1 hundred and 1 ten Write 1 at tens column and carry 1 hundred to the hundreds column.

Step 3

Now, add hundreds: 3 hundreds + 4 hundreds + 1 hundred = 8 hundreds

Step 4

Now add thousands: 6 thousands + 2 thousands = 8 thousands Write 8 in thousands column.

Thus, Areeba and Affan have total amount Rs 8 812.
