No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.
one number will be added

The answer is 39. 3+9=12, 3x9=27. 12+27=39.

To find the final product of 29 multiplied by 16, Garth first multiplied the ones digits (9 and 6) to get 54, which gives him 174 after considering the carry-over. Next, he multiplied the tens digits (2 and 1) to get 2, which he then added to the product of the ones digits to get 176. Finally, he added a zero to the product of the tens digits to get 290 and added this to the previous sum to arrive at the final product of 464.

In a measurement the digits that are an approximation are only those in proper scientific notation. The more digits that are added to the number the more the number becomes exact.

78 times 456 is equal to 35,568. This calculation involves multiplying the two numbers together using the standard multiplication method. To find the product, you multiply the digit in the ones place of the second number (6) by the entire first number (78), then move on to the tens place digit (5) and so on until all digits have been multiplied and added together.
