Answer 1

For this case we must solve the following expression:

$-11 (-7)$

By law of multiplication of signs we have to:

$- * - =+\\- * + = -\\+ * - = -\\+ * + =+$

Also we must find the product of 11 and 7, this is equivalent to:

$11+ 11+ 11+ 11 +11+ 11 + 11 = 77$

Thus, the result of the expression is +77.

$-11 (-7) = 77$
