a) 1946 x 131 + 1000 : 132 x 1946 - 946
= 1946 x ( 131 + 1000 : 132 ) - 946
= 1946 x ( 131 + 7,57 ) - 946
= 1946 x 138,57 - 946
= 268 711,22
a, 7,2/2*28.6+1,43*2*64 (2+4+6+........+98+100)-2264
=3,6*28,6+2,86*64 =2550-2264
=36*2,86+2,86*64 =286
=2,86*(36+64)
=2,86*100=286
b,132*1946-946 1946*131+1000
=256872-946 =254926+1000
