Work: Calculate the value of equation 15*14-14*13+13*12-12*11+0.|+3*2-2*1 .
Question type: Mathematical calculation
Solution:
15*14-14*13+13*12-12*11+0.|+3*2-2*1
=210-14*13+13*12-12*11+0+3*2-2*1
=210-182+13*12-12*11+0+3*2-2*1
=210-182+156-12*11+0+3*2-2*1
=210-182+156-132+0+3*2-2*1
=210-182+156-132+0+6-2*1
=210-182+156-132+0+6-2
=28+156-132+0+6-2
=184-132+0+6-2
=52+0+6-2
=52+6-2
=58-2
=56
Answer:15*14-14*13+13*12-12*11+0.|+3*2-2*1=56
