Four significant digits in 50.00.
2.5000 has five significant digits and 104 has three significant digits. Therefore, the product should have three significant digits, and the answer is "260.". Note that the zero has to be made significant, so a decimal point is needed after the zero or you could put a vinculum (horizontal line) above the zero.

If two numbers have m and n significant digits, respectively, then then product can have at most m+n. However, the normally it is the minimum of m and n.
4.0 x 10-2 * 8.1 x 102 = 32.4 2 significant digits, so the answer is 32.

When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Four significant digits in 50.00.
When multiplying, the product is going to have the same number of significant digits as the least amount in the factors. So 8.08 has three significant digits and 5.232 has four significant digits. Remember that any zeros in-between significant digits is always significant. Because the least amount of sig digs in the factors is three (from 8.08), the product is going to have three sig digs.Multiplying out normally: 8.08 × 5.232 = 42.27456Rounded to three places: 42.3
