Now let's describe in detail how to do it with one, and to be precise, with Omni's multiplication calculator. Nevertheless, this concludes the part about how to multiply without a calculator. To be perfectly honest, the first two were pretty much the same thing it's just that the intermediate steps were in a different order. Similarly, if we keep adding 20 to the next multiples, we get the table of 20. If we add 20 to this number, we get the next multiple.
The multiplication table of 20 is nothing but repeated addition. For us, this translates to putting the dot to the left of 2 2 2, which gives 0.250 = 0.25 0.250 = 0.25 0.250 = 0.25 (we write 0 0 0 if we have no number in front of the dot).Īll in all, we've seen how to multiply decimals in three ways. To obtain the multiplication table of 20, we need to multiply 20 with natural numbers. We then write the dot that many digits from the right in what we obtained. Then we count how many digits to the right of the dots we had in total in the numbers we started with (in this case, it's three: one in 0.2 0.2 0.2 and two in 1.25 1.25 1.25). Add Multiples Of 10 To The Products Of The Table Of 7: Here is another easy trick to learn the 17 times table. When multiplying decimals, say, 0.2 0.2 0.2 and 1.25 1.25 1.25, we can begin by forgetting the dots.
