[2/3 Formula]
    Work: Calculate the value of equation 8+(8+8)+(8+8+8)+(8+8+8+8)+(8+8+8+8+8) .
    Question type: Mathematical calculation
    Solution:
          8+(8+8)+(8+8+8)+(8+8+8+8)+(8+8+8+8+8)
        =8+16+(8+8+8)+(8+8+8+8)+(8+8+8+8+8)
        =8+16+24+(8+8+8+8)+(8+8+8+8+8)
        =8+16+24+32+(8+8+8+8+8)
        =8+16+24+32+40
        =24+24+32+40
        =48+32+40
        =80+40
        =120
    Answer:8+(8+8)+(8+8+8)+(8+8+8+8)+(8+8+8+8+8)=120
