Set up multiplication: We need to multiply 195 by 68. Let's set up the multiplication.195×68
Multiply ones place: First, multiply 8 by 5, which is 40. Write down 0 and carry over 4.195×68−−−−−40 (carry over 4)
Multiply tens place: Next, multiply 8 by 9, which is 72, plus the carried over 4, equals 76. Write down 6 and carry over 7.195×68−−−−−9091 (carry over 7)
Add up numbers: Now, multiply 8 by 1, which is 8, plus the carried over 7, equals 15. Write down 15.\begin{array}{r}\phantom{0}195 (\newline\)\times\phantom{0}68 (\newline\)\hline\phantom{00}60 (\newline\)\phantom{0}760 (\newline\)15__\end{array}
Add up numbers: Now, multiply 8 by 1, which is 8, plus the carried over 7, equals 15. Write down 15.195×68−−−−−601011Next, we multiply the tens place. Multiply 12 by 13, which is 14. Write down 15 and carry over 16.195×68−−−−−60108283 (carry over 16)
Add up numbers: Now, multiply 8 by 1, which is 8, plus the carried over 7, equals 15. Write down 15.195×68−−−−−601011Next, we multiply the tens place. Multiply 12 by 13, which is 14. Write down 15 and carry over 16.195×68−−−−−60108283 (carry over 16)Then, multiply 12 by 86, which is 87, plus the carried over 16, equals 89. Write down 7 and carry over 13.195×68−−−−−60108278 (carry over 13)
Add up numbers: Now, multiply 8 by 1, which is 8, plus the carried over 7, equals 15.

Multiply 6 by 5, which is 10. Write down 11 and carry over 12.\begin{array}{r}\phantom{0}195 (\newline\)\times\phantom{0}68 (\newline\)\hline\phantom{00}60 (\newline\)\phantom{0}760 (\newline\)15000\phantom{0}30\_\text{(carry over 3)}\end{array}Then, multiply 6 by 16, which is 17, plus the carried over 12, equals 19. Write down 7 and carry over 5.\begin{array}{r}\phantom{0}195 (\newline\)\times\phantom{0}68 (\newline\)\hline\phantom{00}60 (\newline\)\phantom{0}760 (\newline\)15000\phantom{0}570\ \text{(carry over 5)}\end{array}Finally, multiply 6 by 1, which is 6, plus the carried over 5, equals 88. Write down 88.\begin{array}{r}\phantom{0}195 (\newline\)\times\phantom{0}68 (\newline\)\hline\phantom{00}60 (\newline\)\phantom{0}760 (\newline\)1500011700\end{array}
Add up numbers: Now, multiply 8 by 1, which is 8, plus the carried over 7, equals 15.
