One can easily find the units digit by looking for a pattern. For numbers with large powers, they will have a pattern that keeps repeating like a cycle. Depending on the multiple of the power, the pattern can be compared to find the units digit.
If x2 + y2 = 1, then the point (x,y) is a point on the unit circle.

To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the hundredths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
Cut it out of a material whose weight per unit of area you know, weigh it, then divide the weight by the weight per unit of area.
It is 63.
The unit digit of 3127173 is the unit digit of 7173. The other digits of 3127 are multiples of 10 and so they cannot contribute to the unit digit. Now the unit digits of the powers of 7 are Power -- Unit digit 0 -- 1 1 -- 7 2 -- 9 3 -- 3 4 -- 1 and you are back into the loop (of 1-7-9-3). So, you only need consider 7 to the power 173 modulo 4. That is, the remainder when 173 is divided by 4. 173 = 1 mod 4 So the unit digit of 3127173 is the same as the unit digit of 7173 which is the unit digit of 71 which is 7.
the unit digit is 4
Any digit in the tens or higher place has no influence on the answer. So it is the unit digit of 4*9*3*6 = unit digit of 6*3*6 = unit digit of 8*6 = 8
It is the unit's digit of the product of the unit's digits. For example, the units digit of 123456 * 4689 is simply the units digit of 6*9 = 54, which is 4.
the unit digit is the last digit from left or ones digit
'5' is the UNIT digit. '6' is the 'tenths' digit. '9' is the 'hundredths' digit.
The unit's digit of x is not 0.
Here's an example. In the number 382, the number 2 is the "unit's digit" (in the "unit's place"), 8 is the "ten's digit" (in the "ten's place"), and 3 is the "hundred's digit."
The unit digit of the square of 81 will be 1.

No. The tens unit is independent of the ones unit
