Question

А)24-(-13)-(-12) б)-33-16-(-11) в)-4.3-5.4-2.6

Answer 1

А) 24+13+12=49
б) -49+11=-38
в) -9.7-2.6=-12.3

Answer 2

А) 24 - (-13) - (-12) To simplify this expression, we can start by removing the double negatives. The expression becomes:

24 + 13 - (-12)

Next, we can simplify the subtraction of a negative number by changing it to addition:

24 + 13 + 12

Now, we can add the numbers together:

24 + 13 + 12 = 49

So, the value of the expression is 49.

б) -33 - 16 - (-11) Similarly, we can simplify this expression by removing the double negatives:

-33 - 16 + 11

Next, we can simplify the subtraction of a negative number by changing it to addition:

-33 - 16 + 11 = -33 - 16 + 11

Now, we can add the numbers together:

-33 - 16 + 11 = -38 + 11

Finally, we can perform the addition:

-38 + 11 = -27

So, the value of the expression is -27.

в) -4.3 - 5.4 - 2.6 To simplify this expression, we can start by performing the subtraction:

-4.3 - 5.4 - 2.6 = -12.3

So, the value of the expression is -12.3.

In summary: а) 24 - (-13) - (-12) = 49 б) -33 - 16 - (-11) = -27 в) -4.3 - 5.4 - 2.6 = -12.3
