explain why it is important to line up decimal numbers by their place value when you add or subtract them
My teacher taught us to subtract with decimal numbers.
0.1333, 0.15, 16
It isn't really that important, it just makes the problem solving easier and gives you less of a chance of making a mistake.
To ensure they are read as binary numbers and not decimal numbers.
Pick any number, A. Subtract 0.653 from A to give the number B. Then (A - B) will give 0.653
This is true for adding and subtracting ALL numbers, not just decimal representations.
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
My teacher taught us to subtract with decimal numbers.
Like you would regular numbers. 12.43 - 5.31 ---------- 7.12
You record the temperatures as decimal numbers and subtract the smaller from the larger.
An easy way is to convert them to decimal, subtract, then convert the answer back to binary.
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
Add, subtract, multiply and divide.
Yes, you can subtract a whole number from a decimal. When doing so, you align the decimal point and perform the subtraction as you would with any other numbers. The result will still be a decimal. For example, subtracting 3 from 5.7 yields 2.7.
When subtracting numbers with significant figures, the answer should be rounded to the same number of decimal places as the number with the fewest decimal places. This ensures that the final answer reflects the precision of the original numbers.
Let the two decimal numbers be x and y. We can set up the equation x - y = 16.825. To find two numbers that satisfy this equation, we can choose any value for x and then subtract 16.825 to find y. For example, if we let x = 20, then y = 20 - 16.825 = 3.175. Therefore, the two decimal numbers are 20 and 3.175.
