Steps

Addition MethodLet's look at how to solve 4 x 3.
  1. Understand that the mathematical sentence above is just another way to say 3 groups of four.
  2. Knowing that each of the four groups have three objects, add 4 three times. 4 + 4 + 4 = 12
Long MultiplicationLet's look at how to solve 187 x 54.
  1. Put the numbers on top of each other and put a line under them like how the picture on the right shows.
  2. Multiply the number on the bottom right with the number above it and then with the number next to it, so on and so forth. If your result hass two digits, put the first digit above the number next to the left of the top first right number. Add the number above it (if any) to the result.
    • 7 x 4 = 28. Place 2 above 8 as shown.
    • 8 x 4 = 32. 32 + 2 = 34. Place 3 above 1 as shown.
    • 1 x 4 = 4. 4 + 3 = 7.
    • Place 0 at where the orange box is. This is just a placeholder for this method to show that you are moving on to multiply the tens place value. 7 x 5 = 35. Place 3 below 2 as shown to avoid confusion.
    • 8 x 5 = 40.40 + 3 = 43. Place 4 below 3 as shown.
    • 1 x 5 = 5. 5 + 4 = 9.
    • Do simple addition and you're done!

Tips

  • It doesn't matter which number is on the top and which number is on the bottom.
  • If you have a three digit number for the second row, you will need two placeholders to move on to multiplying the hundreds place value. For the thousandths place you will need three, so on and so forth.
