Two Digit Multiplication
The first step is
to make sure
the place
values are lined
up.
26
x 12
Tens Ones
Two Digit Multiplication
Begin with
multiplying the
bottom factor’s
one’s place
with the top
factors one’s
place.
1
26
x 12
2
Think, 2 x 6
equals 12.
Because there
is still the
tens place to
multiply, you
must carry
the 1.
Two Digit Multiplication
Next, multiply
the 2 and the
other 2. Then,
remember to
add your carry
of 1.
1
26
x 12
52
Think, 2x2=4+1=5
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.

26
x 12

0
Erase your carry
from before.

Next, begin to
multiply the

Think 1x6=6.
