Write down 320 {\displaystyle 320} , then write 7 {\displaystyle 7} just beneath it, aligned directly below the zero. Draw a 3-digit long line under the 7 {\displaystyle 7} . would denoted two starts, as the lead divided by the pitch is two. The "LH" denotes a left hand thread. [2] Standard pitches for metric diameters [2] Nominal diameter [mm] Write the 7 just to the left of the 48 below the line. It should now read 748 below the line, because you have just calculated 187 ∗ 4 = 748 {\displaystyle 187*4=748} . Multiply the bottom ones place with the top hundreds place. Once again, you repeat the same process as before, but this time use the digit in the ones place (far right) of the bottom number, and the digit in the hundreds place (third from the right) on the top number. And remember to add any carried over digit! [7] X Research source

We can write the answer above using those notation and 38x7 is 266 ft 2 Calculate the Price of a 38x7 Room Solve the ones problem separately. In the current example, the ones problem is 320 ∗ 7 {\displaystyle 320*7} . Your best bet here is probably to do a fairly straightforward example of long multiplication: [15] X Research sourceFor areas of high winds copper annular ring shank nails are the preferred choice. These nails provide much high pull out loads and tests have shown they can be as much as 3 times harder to pull out as smooth shank nails. Multiply 7 {\displaystyle 7} and each digit of the larger number separately, working from right to left. Since 7 ∗ 0 = 0 {\displaystyle 7*0=0} , write a zero under the line, aligned below the 7 {\displaystyle 7} . When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number. For lead flashings, the most common size supplied by tradefixdirect.com is 25 x 3.35mm copper annular ring shank nails.

If you have a project that requires you to calculate the cost of work or materials needed for a 38x7 room or area, the below calculator can help. You can use this guide to calculate the square footage and cost of a building, floor, walls, and more. Multiply as above, but this time write your answers in a new row, shifted one digit place to the left. SKF SNW 38x7 company wins the ISO 14001 environmental management of the global certification. Many SKF subordinate departments, company,factory also passed the ISO 9000 quality management certification or related industry standard authentication. Multiply 7 ∗ 3 = 21 {\displaystyle 7*3=21} , then add 1 {\displaystyle 1} (as indicated by your reminder). Write 22 {\displaystyle 22} just to the left of the 3 {\displaystyle 3} and zero under the line.

Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1. SKF bearing company have more than 80 factories all around the world and there are more than 70 sales department in different countries.It is really a multi-natinal business company.In addition,there are 7000 authorized dealer and distributors for SKF bearings in the world.Meanwhile,with electronic commerce system and global supply system, make SKF company more close to the user, can provide the products and services they need. Anytime, anywhere can satisfy the customers need solutions. Long multiplication with decimals using the standard algorithm has a few simple additional rules to follow. where Sq designates a square thread, 60 is the nominal diameter in millimeters, and 9 is the pitch in millimeters. When there is no suffix it is a single start thread. If there is a suffix then the value after the multiplication sign is the lead and the value in the parentheses is the pitch. For example: Copper nails, depending on the area, can last much longer than galvanised nails. Copper nails must be used in areas of high rainfall, high humidity and high pollution. The most common sizes for slating are 38 x 3.35mm and 30 x 2.65mm

In this article we will show you how to calculate the square feet of an 38x7 room or area and also let you calculate how much your project might cost based on a price per square foot (which is a common thing for household jobs). The greatest disadvantage is the difficulty in machining such a thread. The single-point cutting tools or taps and dies used to cut the thread cannot have efficient rake and relief angles (because of the square form), which makes the cutting slow and difficult. Square threads also cannot carry as much load as a trapezoidal thread, because the root of the square thread is smaller. Also, there is no way to compensate for wear on the nut, so it must be replaced when worn out. [1] Classification [ edit ]Since 7 ∗ 2 = 14 {\displaystyle 7*2=14} , write a 4 {\displaystyle 4} just to the left of the zero under the line, and write a small 1 {\displaystyle 1} just above the 3 {\displaystyle 3} in 320 {\displaystyle 320} . This is your reminder to add 1 {\displaystyle 1} . Typing out the words square feet is quite long winded and if you deal with square feet a lot you'll mostly see it written as either sq ft or ft 2. Use long addition to add your number columns from right to left, carrying as you normally do for long addition. In 187 ∗ 54 {\displaystyle 187*54} , the ones place for the bottom number (54) is still 4, while the hundreds place for the top number (187) is 1. Calculate 4 ∗ 1 = 4 {\displaystyle 4*1=4} , then add the 3 you carried from the previous calculation to get 4 + 3 = 7 {\displaystyle 4+3=7} Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand:
