How do you multiply 2 by 2 digit?
To multiply a 2-digit number by another 2-digit number, you can use the standard multiplication method. Multiply the ones digit of the second number by both digits of the first number and write the results in the appropriate place value positions. Then, multiply the tens digit of the second number by both digits of the first number and place them in the corresponding positions, considering any carry-overs. Finally, add the two partial products to get the final result.
When multiplying decimals where do you move the decimal?
the answer is it stays in the same place.* * * * *Not quite.Suppose you want to multiply two decimal numbers A and B. Multiply the two numbers ignoring the decimal points.Count the number of digits after the decimal point in the number A.Count the number of digits after the decimal point in the number B.Add these two numbers together. This is the number of digits you want after the decimal point in the answer. So count back from the end.Example:2.54 * 3.5 (this is number of centimetres in 3.5 inches)254*35 = 8890Number of digits after the decimal point in 2.54 is 2 (5 and 4).Number of digits after the decimal point in 3.5 is 1 (5).2 + 1 = 3 so there must be 3 digits after the decimal point in the answer.Therefore 8890 becomes 8.890NOW, you can simplify it to 8.89

What number it digits decrease by 2 from the thousands place to the ones place and each number is even number?
If the digits go from the thousands place to the ones place then we need to use 4 digits. Because the digits are all even, we are forced to use the 4 even digits (2, 4, 6 and 8). As they decrease by 2 each time, the only option for ordering them is greatest to lowest. Therefore, the number described in the question is 8,642.
