To compare numbers in scientific notation, compare the coefficients (the numbers before the multiplication symbol) first. The larger coefficient indicates the larger number. If the coefficients are the same, then compare the exponents. A greater exponent implies a larger number, while a smaller exponent indicates a smaller number.

One option for comparing two numbers is to subtract the first number from the second number. If the result is less than zero, the first number is larger. If the result is greater than zero, the second number is larger. If the result is zero, the numbers are equal. Another option (for positive numbers) would be to divide the first number by the second number. If the result is greater than one, the first number is larger. If the result is less than one, the second number is larger. If the result is one, the numbers are equal. This rule flips if you are comparing negative numbers.

Since the integer part is the same (zero vs. zero), compare the FIRST decimal digit. The number with the larger decimal digit is the larger number.

2 3 5 7 2+7 = 9

Since the whole parts are equal, take a look at the FIRST DECIMAL DIGIT - the first digit after the decimal point. The larger number is the one that has the larger digit in this position.

Just compare the first decimal digit. The number that has the larger digit here, is the larger number.

The next prime number greater than 50 is 53.53

Since the whole part of the number is the same (and both are positive), look at the first digit after the decimal point. The number that has the larger digit here is also the larger number.

0.75 is larger. To determine which decimals are larger, always look at the first number after the decimal point. Whichever digit is larger is the larger number. If they're the same, look to the second digit to see which is bigger, and so on. In this case, because 7 is greater than 3, 0.75 is larger than 0.375.

If 0 can be counted as the first number, then the smallest number is 01358. If 0 cannot be counted as the first number, the the smallest number is 10358.
