Numeric value of y.

y = 2.3*10

Without calculator, how? '-'

y = 2.3*10

^{5}+6.1*10^{6}+3.2*10^{7}Without calculator, how? '-'

Er, what exactly are you having trouble with? (e.g. do you know how to compute [itex]10^5[/itex]?)

If i compute 10

32000000+6100000+230000 = 38330000

But if i have 50 questions like that and 1 hour to do all the questions? '-'

Don't have a easy way?

Sorry, my english is bad.

Such a test would still give you over an entire minute per problem!

If it takes you more than a minute to do a problem like this, (even without any shortcuts!) then you just need to practice.

I fully believe if you do a dozen or so practice problems, you'll start to see some short-cuts of your own -- e.g. shorthand for some parts of the numeral, or some parts of the answer you can just write down without having to do any computation at all.

I suspect these short-cuts are probably better figured out on your own than taught. e.g. I could tell you that you didn't really need to write down the last 4 0's of each number in your scratch work, but I doubt me telling you would have the same impact as you figuring a short-cut out yourself after working through enough exercises. It's almost always easier to use your own short-cut than somebody else's short-cut. (even if they are essentially the same thing)

This can be an exercise in managing zeros:

2.3 * 10^5 = 2.3 * 10^5

6.1 * 10^6 = 61. * 10^5

3.2 * 10^7 = 320. * 10^5

Sum = 383.3 * 10^5 = 3.833 * 10^7

The numeric value of y.y represents a specific numerical quantity or measurement.

The numeric value of y.y is typically calculated using a mathematical formula or process involving numbers and operations such as addition, subtraction, multiplication, or division.

Yes, the numeric value of y.y can change depending on the variables or factors that affect it. For example, if the value of y changes, the numeric value of y.y will also change.

The units used for the numeric value of y.y will depend on the context of the measurement. It could be in units of length, time, temperature, or any other unit of measurement.

The numeric value of y.y is important in scientific research because it allows for precise and accurate measurements, which are essential for conducting experiments, analyzing data, and making scientific conclusions.
