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;

}

the pattern appears to be add 5. subtract 4. add 3. subtract 2. so in theory it would be add 1. your answer would be 8

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

add 9 plus 5 than subtract 1 from 5 to add it to 9 will give you 10

That depends what the question is. Do you want to add, subtract, multiply, divide, compare, or what?

18. The pattern is add 5, then subtract 1.

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.

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

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

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 + (1×5)/(2×5) = 1/10 + 5/10 = 6/10 = (3×2)/(5×2) = 3/5
