Step-by-Step Guide to Multiplying Two-Digit Numbers
Understanding the Process:
Let's break down the multiplication of 36 by 27. This process involves multiplying each digit systematically and then combining the results.
Step 1: Multiply the Units Digit
First, we multiply 36 by the units digit of 27, which is 7.
36×736 \times 736×7
Start by multiplying the ones place: 7×6=427 \times 6 = 427×6=42Write down the 2 and carry over the 4.
Next, multiply the tens place: 7×3=217 \times 3 = 217×3=21Add the carried-over 4: 21+4=2521 + 4 = 2521+4=25
Write down 25, giving us 252.
Step 2: Multiply the Tens Digit
Next, we multiply 36 by the tens digit of 27, which is 2 (representing 20).
36×2036 \times 2036×20
We multiply the ones place: 2×6=122 \times 6 = 122×6=12Write down the 2 and carry over the 1.
Multiply the tens place: 2×3=62 \times 3 = 62×3=6Add the carried-over 1: 6+1=76 + 1 = 76+1=7
This gives us 720 (since we are multiplying by 20).
Step 3: Add the Results
Now, add the two partial products:
252+720252 + 720252+720
Align the numbers by place value and add:2 (ones) + 0 = 2
5 (tens) + 2 = 7
2 (hundreds) + 7 = 9
The final result is 972.
Breaking Down the Digits:
Revisiting the example, it's crucial to understand what each digit represents in terms of place value.
36 can be seen as 30 + 6.
27 can be broken down into 20 + 7.
By decomposing these numbers, we can simplify the multiplication process:
36×736 \times 736×7 breaks into:30×7=21030 \times 7 = 21030×7=210
6×7=426 \times 7 = 426×7=42
Add these: 210+42=252210 + 42 = 252210+42=252
36×2036 \times 2036×20 simplifies to:30×20=60030 \times 20 = 60030×20=600
6×20=1206 \times 20 = 1206×20=120
Combine these: 600+120=720600 + 120 = 720600+120=720
Adding the two results, 252 and 720, we again arrive at 972.
