The average. Add all the numbers together and divide that by how many numbers there are. Example: 6,2,3,4,5. Added together equals 20. Divided by all of the numbers (5) equals 4. Your answer would be 4.

The two numbers that multiply together to equal 48 and add together to equal 19 are 12 and 4. When multiplied, 12 × 4 equals 48, and when added, 12 + 4 equals 16. Since these numbers do not satisfy both conditions, the correct pair is actually 16 and 3. They multiply to 48 and add up to 19.
-4 + 10 - 5 + 3 = 13 - 9 = 4 For problems as this, group like terms together : combine the numbers being added and similarly combine the numbers being subtracted.
