Question 1

Subtract.
-0.01 - (-4.674)

Accepted Answer

When subtracting a negative number, it is equivalent to adding the positive version of that number. Therefore, 0.01 - (-4.674) becomes 0.01 + 4.674, which equals 4.684.

Question 2

Simplify.
--13 - 0 - (-20) - 6 + 13

Accepted Answer

The expression simplifies as follows: -13 - 0 + 20 - 6 + 13 = 14.

Question 3

Simplify.
-6 + (-12) + 5 + (-9) + 15 + (-19)

Accepted Answer

When simplifying the expression, group the positive and negative numbers together: (6 + 5 + 15) + (-12 - 9 - 19). This simplifies to 26 + (-40), which equals -14.

Question 4

Subtract.
--2.7 - 0

Accepted Answer

Subtracting 0 from any number leaves the number unchanged, so -2.7 - 0 = -2.7.

Question 5

Simplify.
--8 + 12 - (-19) - 10

Accepted Answer

The expression simplifies as follows: -8 + 12 + 19 - 10 = 13.

Subtract.
-0.32 - 0.11

Accepted Answer

Subtracting 0.11 from 0.32 gives 0.21.

Question 14

Subtract.
--7.1 - 12.9

Accepted Answer

Subtracting a negative number and a positive number involves adding their absolute values and then applying the sign of the initial number. So, -7.1 - 12.9 = -(7.1 + 12.9) = -20.
