STEP 4: Finally, add it up!Add step 2 to step 1 (add your thimble measurement to our sleeve measurement), and then just "tack" step 3 (your vernier measurement) onto the end. As an example, if you're measuring something that is 0.1234", you'd find the .100 on the sleeve (step 1), the .023 on the thimble (step 2), and then you'd add . 023 to .100 for a combined .123. Then, you'd find .0004 on the vernier scale and just tack that onto the end.TECH TIP: Sometimes, for people who are learning this, when you have .123, and you see the .0004 on the vernier scale, it's easy to misunderstand, leave out a zero (.004), add it to .123 and get .127. It's easier to understand if you forget about the zeroes and just put the number from the vernier scale onto the fourth place (the ten-thousandths place), at the end of the .123, to obtain the correct measurement of .1234.
