Can anyone tell me how can brackets change the sign of answer and how to solve them without calculator?
In the first case we have the operation : - 5 * 5 * 5 * 5 = - 625
In the second case we have a parenthesis so the operation is:
(-5) * (-5) * (-5) * (-5) = 625
If we multiply a negative by a positive it gives a negative value
A positive by a positive gives a positive value
A negative by a negative gives a positive value
Got it, Thank you so much🤍
