Write 2-3 as an addition problem. Then simplify the expression.

Write -7 -(-4) as an addition problem. Then simplify the expression.

-1 (-7) as an addition problem. Then simplify the expression.

2 + (-3) = ?

-7 + 4 = ?

-1(-7) = 7 Typo?

To write 2-3 as an addition problem, we can write it as 2 + (-3).

To simplify the expression, we add 2 and (-3), which gives us -1.

To write -7 - (-4) as an addition problem, we can rewrite it as -7 + 4.

To simplify the expression, we add -7 and 4, which gives us -3.

To write -1 (-7) as an addition problem, we can rewrite it as -1 + (-7).

To simplify the expression, we add -1 and (-7), which gives us -8.

To write 2-3 as an addition problem, we need to remember that subtracting a number is the same as adding its opposite. The opposite of 3 is -3. So, the addition problem equivalent to 2-3 is 2 + (-3).

To simplify the expression, we just need to evaluate the addition problem.

2 + (-3) = -1

So, the simplified expression is -1.

Now let's move on to the next expression.

To write -7 - (-4) as an addition problem, we need to remember that subtracting a negative number is the same as adding its opposite.

The opposite of -4 is 4. So, the addition problem equivalent to -7 - (-4) is -7 + 4.

To simplify the expression, we just need to evaluate the addition problem.

-7 + 4 = -3

So, the simplified expression is -3.

Lastly, let's look at -1 (-7).

To write -1 (-7) as an addition problem, we need to recognize that multiplication by -1 is the same as taking the opposite or flipping the sign of the number.

So, -1 (-7) is the same as -1 x (-7).

To simplify the expression, we just need to perform the multiplication.

-1 x (-7) = 7

So, the simplified expression is 7.

2-3=-2
