1.evalute the expression -8 + 15 = 7 is this answer correct?
2.evaluate the expression 19+(+4) = 23 is this answer correct?
3.Evaluate the expression (13) (-4) (-6) = 312 is this answer correct?
4. evaluate |10|+ |-2| =8 is
1,2,3 correct.
4) abs(-2)= +2
2+4-2=4
1. To evaluate the expression -8 + 15, you simply add the two numbers together. In this case, -8 + 15 equals 7. So, the answer is correct.
2. To evaluate the expression 19 + (+4), you add the two numbers together. The positive sign before the 4 indicates that it is a positive number. Therefore, 19 + 4 equals 23. So, the answer is correct.
3. To evaluate the expression (13)(-4)(-6), you multiply the three numbers together. In this case, (-4)(-6) equals 24, and then you multiply the result by 13. So, (13)(-4)(-6) equals 312. Therefore, the answer is correct.
4. To evaluate the expression |10| + |-2|, you calculate the absolute values of each number first, which means removing any negative signs. The absolute value of 10 is 10, and the absolute value of -2 is 2. Then, you add the two absolute values together, which gives us 10 + 2 equals 12. So, the answer is not correct. The correct answer is 12, not 8.
