a) 43 720 - 60 . 7 =
b) 413.2 - 132 • 3 =
c) (9 000 – 8 940) • 9 – (100 000 - 99 960) • 7 =
d) 37 320 – (19 753 + 8 974) - [( 90 • 80 + 143 • 2) - 80 •6] =
e) [100 000 - (10 000 – 8766). 2] - [28 759 - (7 371–80 • 70)]=​

Answer 1

a)

$43720 - 60 \times 7$

$43720 - 420$

$43300$

b)

$413 \times 2 - 132 \times 3$

$826 - 396$

$430$

c)

$(9000 - 8940) \times 9(100000 - 99960) \times 7$

$60 \times 9 - 40 \times 7$

$540 - 280$

$260$

d)

$37320 - (19753 + 8974) - ((90 \times 80 + 143 \times 2) - 80 \times 6)$

$37320 - 28727 - ((7200 + 286) - 480)$

$37320 - 28727 - (7486 - 480)$

$37320 - 2727 - 7006$

$1587$

e)

$(100000 - (10000 - 8766) \times 2) - (28759 - (7371 - 80 \times 70))$

$(100000 - 1234 \times 2) - (28759 - (7371 - 5600))$

$(100000 - 2468) - (28759 - 1771)$

$97532 - 26988$

$70544$
