1 Lakh is written as 1,00,000.00 or in terms of millions, it is 0.1 million.\nTherefore, 1 million is 10 Lakhs

Yes, that is scientific notation format. It is the number 48,000 stated as "4.8 times 10 to the fourth power."\n\n4.8 is called the coefficient; 10 is the base, which in the scientific and mathematic communities is always 10, and 4 is the exponent.\n\nThe exponent is usually offset as a superscript next to the base ten when writing this expression. However, in programming calculations there needs to be an character to indicate the exponentiation. That character is usually a carat, although I've also seen double asterisks.

All the digits used in writing the numbers from 1 to 1000?\nFor the units digit, you use: 100 1's, 100 2's, 100 3's, etc, 100 9's.  So this sum is 100×(1+2+3+4+5+6+7+8+9) = 4500.\nFor the tens digit, it is the same, you use 100 of each.  So this is another 4500.\nFor the hundreds digit, you use another 100 of each, so this is another 4500.\nFor the thousands digit, you use 1 once.\nSo the sum = 4500+4500+4500+1 = 13501

12,000 X 3/8 or 12,000x.375 = 4,500.\n\n12,000-4,500= 7,500.\n\nThe answer is 7,500 more to raise

10 to the 4th power is 4 zeroes after 1 that is 10000.Therefore 3.6X10 the fourth power is 3.6 X 10000.And you know,how easy it is to multiply a number by 10,100 ,1000 or 10000 .just shift the decimal by number of places to the right side as many zero/zeroes are there in the multipler[and if there are not sufficient digits in the multiplicand add required number ot zero/zeroesto the multiplicand  to enable you to shift the decimal.So 3.6x 10000=36000.Now,the second problem d=9.4X10 to the fourth power=9.4 X 10000=94000 km

The rule is that when you're writing numbers you may use a hyphen after the tens place as necessary. And you only do it then if there is something IN the tens space to begin with, and something other than zero in the ones space.  'One hundred twenty-two', 'seventy-four' and 'five hunded thousand four hundred fifty-two' are examples. Also, if the numbers are below twenty, you won't hyphenate, as they names of the numbers are all one word in that case,ie one hundred twelve. Remember that you never use the word "and" unless you have encountered a decimal or fraction. I know you didn't ask that, but it seemed relevant. So, it's not one hundred and twelve, but one hundred twelve. Not two hundred and thirty-four, but two hundred thirty-four:)

Ten numbers per line, add 'em up and divide by 10.\n\nYou should get these means for the four sets:\n\n0.138, 0.172, 0.184, 0.156\n\nBe careful, since not all the numbers may show up on Yahoo unless you put your mouse pointer on the line.

$number = 0.98; \n$formatted_number = number_format ($number, 3);\nif (abs($number) < 1) {\n  $formatted_number = str_replace('0.', '.', $formatted_number);\n}\n\nThis should set $formatted_number to ".980"...

Take each one and put in over 1000 and then reduce.\nYou use 1000 because there are 3 decimal places.

I like using the phrase, "Kangaroos Hop Down University Drive Collecting Money" to remember the terms for kilo, hecto, deca, unit, deci, centi, and milli.  Once you have this down, you can write down the letters K, H, D, U, D, C, M to figure out how to move the decimal.  For example, if you are going from kilograms to decigrams, you would go from K to the second D which is 4 spots to the right, so you would move the decimal four places to the right.  So, 4 kilograms is 40000 decigrams and 60 centimeters is 0.6 meters (two places to the left from M to U).
