Simplify expression inside parentheses: First, let's simplify the expression inside the parentheses and the fraction: 9×(34) becomes 9×4÷3.
Calculate first set of operations: Now, calculate 9×4÷3 which is 36÷3, giving us 12.
Simplify second set of parentheses: Next, simplify the second set of parentheses: (15−(6)/(3)) becomes 15−6÷3.
Calculate second set of operations: Calculate 15−6÷3 which is 15−2, giving us 13.
Combine results of first expression: Now, we have the simplified expression: 2+12−13.
Simplify expression inside parentheses: Add and subtract in order from left to right: 2+12 is 14, and then 14−13 is 1.
Calculate final result: For the second expression, simplify inside the parentheses: −(2+5) becomes −7 and (9−20) becomes −11.
Calculate final result: For the second expression, simplify inside the parentheses: −(2+5) becomes −7 and (9−20) becomes −11.Now, we have the simplified expression: −7−(−11).
Calculate final result: For the second expression, simplify inside the parentheses: −(2+5) becomes −7 and (9−20) becomes −11.Now, we have the simplified expression: −7−(−11).Subtracting a negative is like adding a positive, so −7−(−11) becomes −7+11.
Calculate final result: For the second expression, simplify inside the parentheses: −(2+5) becomes −7 and (9−20) becomes −11.Now, we have the simplified expression: −7−(−11).Subtracting a negative is like adding a positive, so −7−(−11) becomes −7+11.Calculate −7+11 which gives us 4.
Calculate final result: For the second expression, simplify inside the parentheses: −(2+5) becomes −7 and (9−20) becomes −11.Now, we have the simplified expression: −7−(−11).Subtracting a negative is like adding a positive, so −7−(−11) becomes −7+11.Calculate −7+11 which gives us 4.Now, we have the results of both expressions: 1 and 4.
Calculate final result: For the second expression, simplify inside the parentheses: −(2+5) becomes −7 and (9−20) becomes −11.Now, we have the simplified expression: −7−(−11).Subtracting a negative is like adding a positive, so −7−(−11) becomes −7+11.Calculate −7+11 which gives us 4.Now, we have the results of both expressions: 1 and 4.Finally, add the results of the two expressions together: −71.
