If you can do multiplication of two integers without a calculator, then you can multiple an integer (a whole number) with a floating-point number (a number with decimals) without a calculator too.
For example, let us say you want (2.56 * 5).
2.56 * 5
= 2.56 * 5 /1 (I am not changing any value)
= 256 * 5 /100 (I am multiplying the numerator and denominator by 100)
= 1280 /100 (do my multiplication of two integers, 256 and 5)
= 12.8 (do the division)
Note that I am doing the process in the long-hand for illustration purpose. You can take short-cuts once you are comfortable with the process. For example, I shall go straight to multiplying 256 with 5 (ignoring the decimal point; it is like moving the decimal point two places to the right), get the answer, and then move the decimal point two places to the left to return the decimal point to the right location.
==============================
It's easier then you think. First solve it without the decimal in it. then count how many decimals are behind it for both numbers and add it in later.
Here's an example because I'm not good at explaining.
```2.4
`x`5.3
----------
Take out decimals:
```24
`x`53
-----------
1272
easier? now solve it
Because there were one number behind the decimal for both number you add the decimal two spots from right to left
12.72 -- that's your answer try it around and practice.
Heres another example:
34.54
x60.3
---------
?
3454
x603
---------
2082762
2082.762 get it? All you need is practice

Try it out! Do the division! If there is no remainder - or, with a calculator, if you get a whole number without decimals - it is a multiple.
You should be familiar with long division involving decimals
Of course! Without decimals, you couldn't calculate percentages or fractions. Decimals allow you to break a number up. A decimal is basically a fraction, and when you calculate fraction adding, subtraction, multiplication, and division, sometimes it is easier to calculate a fraction by first changing it to a decimal instead.
99 squared, written 992, is the same as 99 x 99 (multiply the number with itself). You can simply do the multiplication.
89 divide by 5 without decimals = 17.8
The IRS does offer a free taz refund calculator. If you vist their website, you should be able to quickly find what you are looking for without a problems!
One cent without decimals can be expressed as 1/100
A calculator is a device used to perform mathematical calculations quickly and accurately. It is commonly used in various fields such as mathematics, science, engineering, and finance to solve complex equations, analyze data, and make calculations efficiently. Calculators can handle a wide range of functions, including basic arithmetic, trigonometry, statistics, and more, making them essential tools for problem-solving and decision-making in many professions and everyday tasks.
Make them into decimals. Make them into decimals.
You can't. Multiple is how you do multiplication
Yes, definitely, in accounting you cannot have a calculator at your side at all times. You need to be able to do complex math problems without the help of a calculator. You also need to know how to use a calculator though, because you can and will have to be able to use one.
