In subtraction, the signs change because subtracting a number is equivalent to adding its negative. For example, subtracting a positive number means you are moving left on the number line, which is the same as adding a negative value. This principle helps maintain consistency in mathematical operations and aligns with the rules of arithmetic, ensuring that the results are predictable and accurate.

Draw the flowchart and explain arithmetic addition and subtraction algorithm with example?
The signs use an exclusive OR gate where if the output is 0, then the signs are the same.Hence, add the magnitudes of the same signed numbers. If the sum is an overflow, then a carry is stored in E where E = 1 and transferred to the flip-flop AVF, add-overflow.Otherwise, the signs are opposite and subtraction is initiated and stored in A.No overflow can occur with subtraction so the AVF is cleared.If E = 1, then A > B.However, if A = 0, then A = B and the sign is made positive.If E = 0, then A < B and sign for A is complemented.
Is subtraction associative why or why not?
No, subtraction is not associative. The associative property states that the grouping of numbers does not affect the result of an operation. For example, in subtraction, (5 - 3) - 2 equals 0, while 5 - (3 - 2) equals 4, demonstrating that changing the grouping changes the result. Thus, subtraction fails to satisfy the associative property.
Why it happens in maths that addition and subtraction makes subtraction?
Ok i can see where you would have trouble with this. When i first started Algebra, i wasn't quite sure how this worked. Here are some examples: 2-+2=0 the subtraction sign cancels the addition out. (2-2 is the same thing) 2- -2= 4 the two subtraction signs make an addition sign. (2+2 is the same thing) I hope i could help you.
What does the word opposite signs mean in math?
In math, "opposite signs" refers to numbers that have different signs, such as positive and negative. For example, +3 and -3 are considered to have opposite signs. This concept is important in various mathematical operations, particularly in addition and subtraction, as it affects the outcome of combining numbers. When two numbers with opposite signs are added, their absolute values are subtracted from each other.
What is the integer rule for combining integers with different signs?
The answer depends on which binary operation you mean when you say "combining". Addition, subtraction, multiplication, division, exponentiation, etc.
What should be done with two subtraction signs?
For example, five minus negative two 5 - (-2) In which case you add the two instead of subtract. 5 + 2 = 7 If there are two 'subtraction' (negative) signs, you add the number.

What does it mean with the signs in algebra?
well the . is multiplication. a number and another number separated with a _ is multiplication. a + is addition, and a - is subtraction. got it? teehee!
What are the addition multiplication subtraction and division signs called?
They are called operators because they operate all of the operators. Hope I helped!
