135 + 246 = 381
You can swap the digits in the hundreds' place between the two numbers, the tens' place and the units' place, for example, 145 + 236 (tens')

List the numbers from least to greatest. Then cancel the numbers out from the left to right.Example0,1,2,3,4,5,6answer=3
When one of the numbers is a multiple of the other.
Yes - but only if the domain is restricted. Normally the domain is the whole of the real numbers and over that domain it must have at least one real zero.
This is known as arranging the numbers in ascending order.
4 x 578 = 2312 8 x 754 = 6032
Assuming you have to use all the digits and use each one exactly once: 135679.

When multiplying numbers with significant digits, count the total number of significant digits in each number. Multiply the numbers as usual, but round the final answer to match the least number of significant digits in the original numbers.
The least possible integer is -98765432. The least possible positive integer is 10234567.

By rearranging the digits the answer is 123.
1) Look at the two numbers you are multiplying 2) Find both their number of significant digits 3) Multiply both numbers together normally 4) Round your answer to the same number of significant digits of the least number in the first two factors 250 x 185 250 had 2 sig. digits------ 185 has 3 sig. digits 250 has the least number of sig. digits (2) Final answer has to have 2 sig. digits Normal answer: 46250 With rounding of sig. digits: 46000
Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.
