Step-by-step explanation:

Given:

The \: numbers \rightarrow -4, 10, 8, 2, -3, -5

To find:

Two expressions that equal 6 using the given numbers

Solution:

Expression first,

Using numbers -4, 2, -3,

aligning the above numbers as,

\frac{ ( - 4 \times ( - 3))  }{2}

will out put 6.

<em>Verification,</em>

\frac{ ( - 4 \times ( - 3))  }{2} =  \frac{12}{2}   = \cancel\frac{12}{2} = 6

Expression second,

Using numbers 10,8,2,-5

aligning the above numbers as,

\frac{ - ( - 5 \times 8)}{10} + 2

will result 6.

<em>Verification</em>

\frac{ - ( - 5 \times 8)}{10} + 2 =  \frac{ 40}{10}  + 2   \\ \\ \frac{ - ( - 5 \times 8)}{10} + 2= 4 + 2 \\  \\\frac{ - ( - 5 \times 8)}{10} + 2  = 6
