Question

Jonas cell phone came with 64 GB of memory. He has used 15 GB. He then uses 5 MB of memory to record photos and videos from a trip. Using addition expression 64 plus negative 15 plus negative. 5 to find out how much memory is left.

Answer 1

Answer: 44 GB of memory left

Explanation:

64 + (-15)+ (-5) = 64-15-5= 44

Answer 2

Answer: 44 GB

Explanation:

To find out how much memory is left on Jonas' cell phone, we can use the addition expression: 64 + (-15) + (-5).

First, let's add 64 and (-15). When we add a positive number and a negative number, we subtract the smaller absolute value from the larger absolute value, and give the sum the sign of the number with the larger absolute value. In this case, the absolute value of 64 is larger than the absolute value of -15, so we subtract 15 from 64. This gives us 49.

Now, let's add 49 and (-5). Again, we subtract the smaller absolute value from the larger absolute value, and give the sum the sign of the number with the larger absolute value. The absolute value of 49 is larger than the absolute value of -5, so we subtract 5 from 49. This gives us 44.

Therefore, Jonas has 44 GB of memory left on his cell phone
