2. 153+(-97)+63+(-54)

3. 1095+(-98)+20+(-33)​

Answer 1

=-6 - 12 +15-8
=-18+15-8
=-3-8
=-11


=153-97+63-54
=56+63-54
=119-54
=65

=1095-98+20-33
=997+20-33
=1017-33
=984

Hope it helps you

Answer 2

Given,

$(-6)+(-12)+15+(-8)$

$153+(-97)+63+(-54)$

$1095+(-98)+20+(-33)$

We have to simplify the above

Let us do one by one

As we know that the mathematical operations

$(+)\times(-)=(-)\\(-)\times(+)=(-)\\(+)\times(+)=(+)\\(-)\times(-)=(+)$

Using these we have to solve

1) $(-6)+(-12)+15+(-8)$

By using mathematical operations.

We get,

$-6-12+15-8$

Add all the minus terms together we get

$-26+15$

$-11$

2)$153+(-97)+63+(-54)$

By using mathematical operations.

We get,

$153-97+63-54$

Add all the minus terms together and plus terms we get,

$216-151$

$65$

3)$1095+(-98)+20+(-33)$

By using mathematical operations.

$1095-98+20-33$

Add all the minus terms together and plus terms we get,

$1115-131$

$984$

Therefore, the values of given expressions are $-11$,$65$,$984$.
