Math question for the number 4: How many ways can 4 be expressed as the sum of smaller positive integers?

The number 4 can be expressed as the sum of smaller positive integers in 5 unique ways: 4+0, 3+1, 2+2, 2+1+1, and 1+1+1+1. This can be determined by examining all possible combinations while considering the order of the numbers. Each sum is distinct, and there are no more possibilities as the remaining numbers would be less than 1, yielding only repetitions. Therefore, there are 5 ways to express 4 as the sum of smaller positive integers.

Math question: What is the cube of 4?

To find the cube of 4, we multiply 4 by itself twice. 4² equals 4 * 4 = 16, and then multiplying 16 by 4 gives us 16 * 4 = 64. Hence, the cube of 4 is 64.

Math question: What is the sum of all positive integers from 1 to 4?

The sum of positive integers from 1 to 4 can be calculated using the formula for an arithmetic series: (n/2) * (first term + last term), where 'n' represents the number of terms. In this case, n=4, the first term is 1, and the last term is 4. Plugging these values into the formula gives: (4/2) * (1 + 4) = 2 * 5 = 10. Therefore, the sum of all positive integers from 1 to 4 is 10.
