If we are moving from a large value to a small value we move the decimal point to the left.
Move it to the left.

One unit to a unit which is a multiple of ten times as small.
if a mans shoe size is 9 is it a small medium or large
That is not what mathematicians mean by an irrational number, which is a number with an infinitely long decimal expansion. You will note that since division is the inverse of multiplication, dividing by small numbers has the same effect as multiplying by large numbers, and so dividing by zero, which is an infinitely small number, is equivalent to multiplying by infinity. The result in most cases is deemed to have no mathematical meaning.

Exponential notations are ways of writing very large or very small numbers using exponents. The first step is to add or move the decimal point. For a number like 0.00435 you move the decimal to make it 4.35, or for 345,000 the decimal would be 3.45. After moving the decimal you count how many spaces. If the decimal moved to the right then it looks like 4.35*10^-3 and when moving left it would read 3.45*10^5.
0.0000000000000000000000000000000000001 is a very small decimal number. ^^
Scientific notation is a way of representing numbers, usually very large or very small, in the forma*10b where 1 ?|a| < 10 is a decimal number and b is an integer (negative or positive).a is called the mantissa and b is called the exponent.To convert a number to scientific notation:
Scientific notation is a way of representing numbers, usually very large or very small, in the forma*10b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive).a is called the mantissa and b is called the exponent.To convert a number to scientific notation:· If the number has no decimal point, then add one at the end.· Then move the decimal point to just after the first digit while counting the number of places you have moved it.· The new number, formed after moving the decimal point is a.· The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.For example:23045.06 becomes 2.304506*1040.00023004 becomes 2.3004*10-4

Scientific notation is used to express very large or very small numbers. instead of writing 15,000,000, you can express the same number by writing it as 1.5 * 107 or, you could express the very small number .00000015 as 1.5 * 10-7 to express a number in scientific notation, simply place a decimal point after the first number (in a large number) or before the last number (in a very small number) and multiply by ten to the nth power, where n is the number of digits following the decimal point (in a large number) or negate the number of digits before the decimal (in a very small number).
