See a solution process below:

We can rewrite this expression as:

$2 \times 11 \times - 2 \times 10 \Rightarrow$ $2 xx 11 xx -2 xx 10 =>$

$2 \times - 2 \times 11 \times 10 \Rightarrow$ $2 xx -2 xx 11 xx 10 =>$

$(2 \times - 2) \times (11 \times 10) \Rightarrow$ $(2 xx -2) xx (11 xx 10) =>$

$- 4 \times 110 \Rightarrow$ $-4 xx 110 =>$

$- 440$ $-440$

$= - 440$ $=-440$

$22 \times - 20$ $22 xx -20$

When you are multiplying a positive number with a negative number, the result has to carry the negative sign.

$22 \times - 20 = - 440$ $22 xx - 20 = -440$

How do you evalaute 22×−20=22\times - 20=?
