Find the value of -20+ (-)+(-150)-300

=−470

Step-by-step explanation:

−20−100−(−100)−150−300

=−120−(−100)−150−300

=−20−150−300

=−170−300

=−470

- 470.

Step-by-step explanation:

-20+ (-100)-(-100)+(-150)-300

Distributing the negative over the parentheses (recall that -* - = + and - * + = -)

= -20 - 100 + 100 - 150 - 300

= 100 - 100 - 20 - 150 - 300

= 100 -  570

= - 470.
