Answer 2

$\bf \red{( - 61) \div [( - 60) + ( - 1)] = 1}$

Given:

• $( - 61) \div [( - 60) + ( - 1)]$

To find:

• Evaluate the mathematical expression.

Solution:

Points to remember:

• (+)×(-)= (-)i.e.; if two numbers having (-) sign and (+) sign are multiplied then sign of resultant is (-).
• (-)+(-) = (-),i.e.; if two numbers having (-) sign,they both add and sign of resultant is (-).

Step 1:

Open last brackets.

$( - 61) \div ( - 60 - 1)$

Step 2:

Add -60 and -1.

$(- 61) \div ( - 61)$

or

$= \frac{ - 61}{ - 61}$

or

$( - 61) \div [( - 60) + ( - 1)]= 1$

Thus,

$\bf ( - 61) \div [( - 60) + ( - 1)] = 1$
