Two of them and they are 23
When rounding 233.356 to two significant figures, we start counting from the leftmost non-zero digit. In this case, the first two digits are 2 and 3. The digit following the last significant figure (3) is 3, which is less than 5, so we do not round up. Therefore, 233.356 rounded to two significant figures is 230.

12:02 am ( two minutes past midnight) is ' 0002 ' on the 24 hour clock. NB On the 24 hour clock , the time ' 0000 ' or ' 2400 ' is NEVER used . This is to avoid confusion , over the day / date. NNB The latest time is 2359 hours and the earliest time is ; 0001 hour NNNB The 24 hour clock is divided as follows. The left hand two figures refer to the hour and the right hand two figures refer to the minutes in the hours. '. Hence the first(left) two figures only range from '00' to' 23' and the second (right) two figures only range from '00' to '59'.

A number with two significant figures is 0.045. In this example, the leading zeros are not counted as significant; thus, only the digits "4" and "5" are considered significant figures. Another example is 23, where both digits are significant.
To determine the number of significant figures in the product of 0.1400, 6.02, and (10^{23}), we need to identify the significant figures in each number. The number 0.1400 has four significant figures, 6.02 has three significant figures, and (10^{23}) has one significant figure (as it is a power of ten). The product will have the same number of significant figures as the term with the least significant figures, which is 6.02 with three significant figures. Therefore, the final product will have three significant figures.
