1 answer:
Ahat [919]2 years ago
7 0

Step-by-step explanation:

what answer is needed ? the result of the calculation ?

I assume this is the case.

remember that regarding the sequence of operations brackets are first, then exponents, then "dot" operations (× and ÷), and only at the very least come the "dash" operations (+ and -).

and that a combination of - + or + - results in -.

14 + 16 ÷ 2³ - (12 + 3²) ÷ 7 + 2 × (-5) =

14 + 16 ÷ 2³ - (12 + 9) ÷ 7 - 2 × 5 =

14 + 16 ÷ 2³ - 21 ÷ 7 - 2 × 5 =

14 + 16 ÷ 8 - 21 ÷ 7 - 2 × 5 =

14 + 2 - 3 - 10 = 3

Find the difference!!!!!!!!!!!!!!!!!!11
pav-90 [236]

Answer:

-4

Step-by-step explanation:

-10 - (-6)

Remove the brackets:

-10 - - 6

Remember that all negative and negative values are always positive because they are the same; if they are different, for instance, a positive value and a negative value, then that value will be a negative value.

Continue solving:

-10 - - 6

- and - are positive values

- 10 + 6

= - 4

Therefore the answer is 4
