=986 x 100 - 100
=98600 - 100
= 98500
\(986.\left(56+44\right)-100=986.100-100=98600-100=98500\)
986× (56+44)-100
= 986 × 100-100
= 986 × (100-100)
= 986 × 0= 0
\(986.\left(56+44\right)\)\(-100=986.100-100=98600-100\)\(=98500\)
986 * ( 56 + 44 ) - 100
= 986 100 - 100
= ( 986 - 1 ) * 100
= 985 * 100
= 98500
986 x (56+44)-100
= 986 x 100-100
= 986 x 0= 0
\(986\times(56+44)-100\)
\(=986\times100-100\)
\(=100\times(986-1)\)
\(=100\times985\)
\(=98500\)
