There is no sequence of adds or subtracts of 5, 6, 8, 9, and 10 that sum to 1. Check it with this C++ code...

for (int i=0; i<32; ++i) {

int sum = 0;

if (i&1) sum += 5; else sum -= 5;

if (i&2) sum += 6; else sum -= 6;

if (i&4) sum += 8; else sum -= 8;

if (i&8) sum += 9; else sum -= 9;

if (i&16) sum += 10; else sum -= 10;

cout << i << " " << sum << endl;

}

### What is the roman numeral DCI-X equal?

DCI is 601. D = 500, C = 100, and I = 1, so 500 + 100 + 1 = 601.Now subtract 10 [X means 10], so 601- 10 = 591.So 500 = D, and then add 91. So 91 = 90 + 1. To get 90, do XC [100 - 10], then add 1 for XCI, so it is DXCI.

### What are three arithmetic means between -2 and 12?

Any number can be an arithmetic mean. SO just pick any three numbers between -2 and 12. And if you want to find a set of numbers for which your selected number is a mean add 1 and subtract 1 from it, or add 2 and subtract 2 from it (or do both). Suppose you pick 8. Add 1 and subtract 1: 7 and 9. 8 IS the arithmetic mean of 7 and 9. Add 2 and subtract 2: 6 and 10. 8 is the arithmetic mean of 6 and 10. It is also the AM of 6, 7, 9 and 10.

Subtract the numerator Subtract or add the numerator Subtract or add the numerator ex: 3/4-1/4=2/4 or 1/2 ex: 5/8 + 1/8= 6/8 or 3/4

### What is the difference between adding and subtracting fractions?

to add a fraction, get a common denominator, then add the numerators. example: 2/10+4/5 first get common denominators 2/10+8/10 then add the numerators 10/10 (simplify) 1 to subtract from a fraction, get common denominator, then subtract the numerators. example: 4/5-2/10 first get common denominators 8/10-2/10 then subtract the numerators 6/10 (simplify) 3/5

### What is one tenth add one half?

To add/subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are added/subtracted and the resulting fraction simplified: 1/10 + 1/2 = 1/10 + (1&times;5)/(2&times;5) = 1/10 + 5/10 = 6/10 = (3&times;2)/(5&times;2) = 3/5
