Multiply By Two Digits

Let’s Review Factors- Numbers multiplied together Product- The answer in a multiplication equation

23 x 12 Let’s estimate by rounding-

Two Digit Multiplication 23 x12 The first step is to make sure the place values are lined up. OnesTens

Two Digit Multiplication 23 x12 Begin with multiplying the bottom factor’s one’s place with the top factors one’s place. Think, 2 x 3 equals 6. 6 Circle the multiplier.

Two Digit Multiplication 23 x12 Next, multiply the 2 and the other 2. Think, 2x2=4 64

Two Digit Multiplication 23 x12 We are done with the first multiplier. Cross it out and circle the next multiplier (tens). 64 0 We need to use a 0 for a place holder. Place the 0 under the 6 in the products line.

Two Digit Multiplication 23 x12 Next, begin to multiply the 1in the tens place with the top line factor. Think 1x3=3. 64 03

Two Digit Multiplication 23 x12 Think 1x2=2. 64 032

Two Digit Multiplication 23 x12 Finally, add the two product lines to find the final product. 64 032+ 672 Add the ones place. Add the tens place. Add the hundreds place. 2 X 23= 46 10 X 23= 230

The product is 276

34 x 19 34 x 19 1. 656 2. 646 3. 677 4. None of these

Two Digit Multiplication 34 x19 60 0 43 + 646 3 3

54 x 23 54 x 23 1. 1,242 2. 1,244 3. 1,342 4. 1,142

Two Digit Multiplication 54 x23 26 0 8 10 + 242 1 1 1

41 x 18 41 x 18 1. 748 2. 778 3. 738 4. 728

Two Digit Multiplication 41 x18 82 0 1 4 + 837 3

68 x 35 68 x 35 1. 2,370 2. 2,345 3. 3,270 4. 2,380

Two Digit Multiplication 68 x35 04 0 4 20 + 083 4 3 2 2

76 x 52 76 x 52 1. 3,952 2. 4,952 3. 3,852 4. 3,552

Two Digit Multiplication 76 x52 25 0 0 38 + 259 1 1 3 3

94 x 76 94 x 76 1. 7,044 2. 7,144 3. 6,044 4. 6,244

Two Digit Multiplication 94 x76 46 0 8 65 + 441 2 5 7 2
