Question

In a quiz , team A scored 20 , - 10 , 34 and team B scored - 10 , 20 , 34 in three successive rounds. Which team scored more​

Answer 1

$\huge{\underline{Integers}}$

Score of Team A = 20, -10 , 34

= 20 +(-10)+34

=20-10+34

=20+34-10

=54-10

=44

Score of Team B

= -10,20,34

= -10+20+34

=10+34

=44

Answer ==> Both the teams scored equal.

We can also conclude that we can add integers in any way as it is closed by the commutative property of addition of Integers.

Few things to be kept in mind , while adding or subtracting integers

- and + = -

+ and - = -
