How to Multiply By Two Digits

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

Two Digit Multiplication The first step is to make sure the place values are lined up. 26 x 12 Tens Ones

Two Digit Multiplication 1 Think, 2 x 6 equals 12. Begin with multiplying the bottom factor’s one’s place with the top factors one’s place. 26 x 12 Because there is still the tens place to multiply, you must carry the 1. 2

Two Digit Multiplication Think, 2x2=4+1=5 1 Next, multiply the 2 and the other 2. Then, remember to add your carry of 1. 26 x 12 5 2

Two Digit Multiplication Next, because we are going to the next place value (tens), we need to use a 0 for a place holder. Place the 0 under the 2 in the products line. Erase or mark out your carry from before. 1 26 x 12 5 2

Two Digit Multiplication Next, begin to multiply the 1in the tens place with the top line factor. Think 1x6=6. 26 x 12 5 2 6

Two Digit Multiplication Think 1x2=2. 26 x 12 5 2 2 6

Two Digit Multiplication Add the ones place. Carry if necessary. Finally, add the two product lines to find the final product. 26 Add the tens place. Carry if necessary. x 12 5 2 Add the hundreds place. Carry if necessary. 1 + 2 6 3 1 2

The product is 312

Congratulations! You can now multiply 2 digit numbers by 2 digit numbers!
