Question

David and Victoria are playing the integer card game. David drew three cards -6,12,and-4.What is the sum of the three cards in his hands?

Answer 1

For this case we have that David drew the cards given by:

• -6

• 12

• -4

We have:

$x = -6 + 12-4$

Where "x" represents the sum of the cards that David drew.

To add, we first group similar terms:

$x = -6-4 + 12$

Taking into account that equal signs are added and the same sign is placed, we have:

$x = -10 + 12$

Taking into account that different signs are subtracted and the sign of the major is placed, we have:

$x = + 2$

Thus, the sum of David's three cards is$x = 2$

Answer:

The sum of David's three cards is 2
