Multiplication Table for 2, 3, 4 and 5
Suppose you want to multiply 25.3 by 0.46.
Pretend that you’re multiplying numbers without decimal points:
Now you need to find out where the decimal point goes.
To do this, notice that 25.3 has one digit after the decimal point, and that 0.46 has two digits after the decimal point.
Place the decimal point in the answer so that it has three digits after the decimal point.
Suppose we want to multiply 57 by 13. First we multiply 57 by 3 to get 171 .
Next we multiply 57 by 1..
1 is in the tens column so it really means 10. We have to put a 0 directly under the 1 in 171.
Now we can multiply 57 by 1 to get 57.
To finish up, add the two products
So 57 multiplyed by 13 is 741. Continue reading Multiplying Larger Numbers
