Question

First Question. How can you find the total value when adding positive and negative values?
2nd Question. How can we predict whether the addition of 2 numbers will equal a positive number, negative number, or zero?
3rd Question. How does knowing the algorithms for operations involving integers help us solve expressions or equations?

Answer 1

Answer:

1. 0 : because all positive values have additive inverse (negative value) and their sum is 0

2. if both the numbers are equal and with different signs then they addition will become zer0 when the number with negative sign is higher than the number with positive sign then the answer will be negative or else if both the numbers are negative the answer will be of negative , if they both are positive then the answer is positive and when they are of opposite signs then if the positive number is greater than negative number then the answer is poisitve

3. equation and expressions are composed of operations and algorithms and we use our algorithms to reduce the expression to the

maximum

Answer 2

Answer:

here is your answer

Step-by-step explanation:

1) while addition or subtraction, don't consider the sign first add or subtract, after this , see which number is bigger, accordingly take the sign .

2) it is only possible after solving the question, it would be better to do rough then write the final answer.

3) if we follow the algorithm, there are less chances of doing mistakes and in exams if it is a long type question,u can get full marks.
