(1) How much minus 4 and 1 / 3 plus = minus 2? (2) how much minus 6 and 1 / 4 = 2 and 1 / 12?

1) Two and a third
2) Minus four and one third

One thousand nine hundred eighty eight times four fifths plus four fifths times thirteen minus four fifths

1988*（4/5+4/5*13-4/5）=20675.2
1988*4/5+4/5*13-4/5=1600

Four fifths minus (thirteen sixteenth minus five sixteenth) plus three fourths
The brackets count first

Four fifths minus (thirteen sixteenth minus five sixteenth) plus three fourths
=4/5-1/2+3/4
=16/20-10/20+15/20
=21/20
