Answer :

Sure! Let's solve the expression step-by-step.

We have the expression:
[tex]\[ -657 - 139 \][/tex]

Step 1:
Rewrite the expression by combining the terms. Subtracting a positive number is the same as adding its negative. So we can rewrite:

[tex]\[ -657 - 139 = -657 + (-139) \][/tex]

Step 2:
Add the two negative numbers together by combining their absolute values, and then placing a negative sign in front of the result.

[tex]\[ |-657| = 657 \][/tex]
[tex]\[ |-139| = 139 \][/tex]

Now add the absolute values:

[tex]\[ 657 + 139 = 796 \][/tex]

Step 3:
Since both numbers were originally negative, the result will also be negative:

[tex]\[ -796 \][/tex]

So, the result of the calculation [tex]\( -657 - 139 \)[/tex] is:

[tex]\[ -796 \][/tex]
