How is multiplying a 2-digit number by a 1-digit number the same as multiplying a 3-digit number by a 1-digit number and how is it different?
Multiplying a 2-digit number by a 1-digit number involves multiplying the digits in the ones and tens place and then adding the products. Similarly, multiplying a 3-digit number by a 1-digit number follows the same principle, where you multiply the digits in the ones, tens, and hundreds place and then add the products. The main difference is that in the latter case, you are dealing with three sets of digits to multiply and add, whereas in the former, you only have two sets of digits.
If you add a two digit number to a two digit number can you get a four digit number?
Well, friend, when you add two two-digit numbers together, the sum will always be a two-digit number or a three-digit number, not a four-digit number.

What computation method would you use to find 23 x 18?
To find the product of 23 and 18, you would use the standard multiplication method. Start by multiplying the units digit of the first number (3) by the units digit of the second number (8), which equals 24. Write down the 4 and carry over the 2. Then, multiply the units digit of the first number by the tens digit of the second number, and vice versa, and add the carried over digit. Finally, multiply the tens digit of the first number by the tens digit of the second number and add it to the total. The result of 23 x 18 is 414.

What is an easier way to find the factors of a number?
You can reduce the number by known factors to make it more manageable. Plus there are tricks for different numbers: If the number is even, then 2 is a factor. If the digits add up to a multiple of 3 then 3 is a factor. If the ones digit is a 5 or 0 (with a tens digit greater than or equal to 1), then 5 is a factor. If the ones digit is a 0 then 10 is a factor. If the digits have the property that the first minus the second, plus the third, minus the fourth, (alternating signs) equals 0, then 11 is a factor. There are other tricks but these factors would be the most common.
