Partial Products Multiplication Step by Step

742 X 29 742=700+40+2 Expand each number.

742=700+40+2 29 = 20+9 Expand each number. 742 x 29

742=700+40+2 29 = 20+9 Multiply 700 x 20. 742 x 29 700 x 20 = 14000

742=700+40+2 29 = 20+9 Multiply 700 x 9. 742 x 29 700 x 20 = 14000 700 x 9 = 6300

742=700+40+2 29 = 20+9 Multiply 40 x 20. 742 x 29 700 x 20 = 14000 700 x 9 = 6300 40 x 20 = 800

742=700+40+2 29 = 20+9 Multiply 40 x 9. 742 x 29 700 x 20 = 14000 700 x 9 = 6300 40 x 20 = 800 40 x 9 = 360

742=700+40+2 29 = 20+9 Multiply 2 x 20. 742 x 29 700 x 20 = 14000 700 x 9 = 6300 40 x 20 = 800 40 x 9 = 360 2 x 20 = 40

742=700+40+2 29 = 20+9 Multiply 2 x 9. 742 x 29 700 x 20 = 14000 700 x 9 = 6300 40 x 20 = 800 40 x 9 = 360 2 x 20 = 40 2 x 9 = 18

742=700+40+2 29 = 20+9 Now, add all you products. 742 x 29 700 x 20 = 14000 700 x 9 = 6300 40 x 20 = 800 40 x 9 = 360 2 x 20 = 40 2 x 9 = + 18 21,518

742 x 29 = 21,518
