Question
Find the value of:
38 - (-25) - 58 + (-15) + 23 - (-8)
38 - (-25) - 58 + (-15) + 23 - (-8)
✓
Answer
38 - (-25) - 58 + (-15) + 23 - (-8)
= 38 - (-25) - 58 + (-15) + 23 + 8
= 38 - (-25) - 58 + (-15) + 31
= 38 - (-25) - 58 + (31 - 15)
= 38 - (-25) - 58 + 16
= 38 - (-25) - (58 - 16)
= 38 - (-25) - 42
= 38 + 25 - 42
= 38 - (42 - 25)
= 38 - 17
= 21
Hence, 38 - (-25) - 58 + (-15) + 23 - (-8) = 21
= 38 - (-25) - 58 + (-15) + 23 + 8
= 38 - (-25) - 58 + (-15) + 31
= 38 - (-25) - 58 + (31 - 15)
= 38 - (-25) - 58 + 16
= 38 - (-25) - (58 - 16)
= 38 - (-25) - 42
= 38 + 25 - 42
= 38 - (42 - 25)
= 38 - 17
= 21
Hence, 38 - (-25) - 58 + (-15) + 23 - (-8) = 21
