ADDITION OF 4-DIGIT NUMBERS (WITHOUT CARRY OVER)
Addition
1. Add 4523 and 1236. Spirally organised

exactly should we get. Three more
we need. Let’s go and get. Step 2: Add the tens, 2 + 3 = 5
Step 3: Add the hundreds, 5 + 2 = 7
Step 4: Add the thousands, 4 + 1 = 5
Thus, 4523 + 1236 = 5759
Warm-up connects 2. Find: 1450 + 1234 + 315
We arrange the numbers in proper columns and add columnwise.
to concepts Th 1 1 H 4 2 T 5 3 O 0 4
+
2 3 9 1 9 5 9
So, 1450 + 1234 + 315 = 2999.
