Question

71 - 83 - (-42) + 15 explain me step by step ​

Answer 1

Answer:

45

Step-by-step explanation:

First we will open the brackets

so,

71-81 +42+15 (– & – = +)

-12+57 ( because 81 is bigger than 71 therefore –12)

(– & + = – but sign will be + because 57 is grater than 12)

-12+57= 45

Answer 2

$= 71 - 83 - ( - 42) + 15$

$= 71 - 83 + 42 + 15$

$= - 12 + 57$

$= 45$
