When should a digit be rounded up and when should it be rounded down?
When the digit immediately to the right of it is 0-4 round down. If it is 5-9 round up.
How do you round each number to the place of the underlined digit?
When rounding to a specific place, take a look at the digit immediately to the right of the target. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.
How do you round a 4 digit number to the nearest 10?
Look at the last digit. If it is a zero, it does not need to be rounded. 4870 does not change. If it is 1, 2, 3 or 4, it is rounded down, replacing that digit with a zero. 5214 becomes 5210. If it is 5, 6, 7, 8 or 9, it is rounded up, so the digit becomes zero and the digit beside it is incremented by one. 8176 becomes 8180.
What is 58.933 rounded?
