In most mathematics, it is implied that all numbers are positive. Negative numbers are invariably shown prefixed by a -ve sign. To help clarification, a positive number may occasionally be shown preceded by a +ve sign.
The subtraction of a positive number equates to the addition of a negative number.
EXAMPLE : 7 - 2 = 5 equates to 7 + (-2) = 5

Negative - a positive would make it keep it change it change it so the problem would look like this -8 + -2 = -6, Im in honors math just to let you know, with all the subtraction problems, if they are integers,you do keep it change it change it keep the first digit and don't do anything to it change the subtraction sign to an addition sign and if the next integer is positive make it a negative if it is a negative make it a positive.
THE ANSWER TO a subtraction problem is difference! just look it up and leave me alone for the others that come on this sight hey i added this to my favorites !! I dont have to do hw in school!! lol jk .
Order of operations is very helpful in solving many problems. First, you check for parenthesis, then exponents, then multiplication/division, then subtraction/addition. For example with the problem 2+3(9-2)+(3^2), you would first look for parenthesis from left to right. The first parenthesis is (9-2) and therefore you solve the contents of those parenthesis, resulting in (7). So now your problem reads 2+3(7)+(3^2). Your second set of parenthesis (from left to right) is (3^2), which results in 9 when solved. Now, your equation is 2+3(7)+(9). There are no longer any parenthesis that are solvable (the contents of all the parenthesis are all simplified), therefore you check for multiplication/division. When a number is next to another number (or variable for that matter) without any operation signs like addition, subtraction, multiplication, or division, you will multiply those numbers. (aka 3(7)=3 times 7). So, your only (and inherently first) multiplication operation in the equation is 3(7), which results in 3 times 7, which is equal to 21. Now, your equation reads 2+21+9. You now look for subtraction/addition from left to right. The first addition problem in the equation is 2+21which results in 23, meaning your equation now looks like this: 23+9. Your next addition in the equation is 23+9, which simplifies to 32. Therefore, 2+3(9-2)+(3^2)=32.
The answer is simple: Grouping symbols Exponents Multiplication Division Addition Subtraction Follow each step by checking to see if the problem qualifies under that word/s. so first: grouping symbols. Since there are none, move on to exponents. next: check for exponents.none, so move on to multiplication. next: multiplication. do all sections that require multiplication, so: 5x6=30 and 3x3 = 9. so replace those with the new numbers. Next: division. none, so move on. Next: addition. add 9 to 4 and 30 to 3. so now your problem should look like this: 33-13=? next: subtraction. the last step is to simply subtract 13 from 33 and your answer should be.......20!
