Answer 2

Answer:

10

Step-by-step explanation:

The rule is: "To find the sum of two numbers with different signs, we have to find the difference between absolute value of given numbers and at the end use the sign of bigger of absolute number.

(- 20) + (+ 30)

| - 20 | = 20

| + 30 | = 30

30 - 20 = 10

| + 30 | > | - 20 | ⇒ the sum is positive

(- 20) + (+ 30) = 10

[ (b). (+ 10) + (- 12) = - ( 12 - 10) = - 2 ]

In fact :

When we add the number with the same signs, we have to add their absolute value and at the end use their common sign.

(d). ( - 7) + (- 3) = - (7 + 3) = - 10

(e). ( - 20) + ( - 30) = - (20 + 30) = - 50

----------------

(+ 5) + (+ 11) = + (5 + 11) = + 16 = 16 :)
