. Verify :
(0) 37 x {8+ (-3)} = 37 8 + 37 (-3)
(ii) (-82) {(-4) + 19} = (-82) (-4) + (-82) x 10
(iii) {7 - (-7)} * 7 = 7x7 -(-7)x7
(iv) {(-15) - 8} -6 = (-15) * (-6) – 8 x (-6)

1) 1925*101-1925
=(1925 * 101) - 1925
= 194425 - 1925
= 192500
2) 37*{8+(-3)} = 378 + 37 (-3)
= 37* (8-3) = 378 + (-111)
= 37* (5) = 378 -111
= 185 = 267
So both are not equal
3) (-82) {(-4) + 19} = (-82) (-4) + (-82)*10
= (-82){15} = (328) + (-820)
(-1230) = (-492)
So both are not equal
4) {7-(-7)}*7 = 7*7-(-7) *7
=(14)*7= 7*{7-(-7)}*7
=98 = {7*(14)}*7
= 98 = (98)*7
= 98 = 686
So both are not equal
5) {(-15)-8}-6= (-15)*(-6)-8*(-6)
= {(-23) -8} -6 = {(-15)*(-6)} - {8*(-6)}
=(-31) - (-6) = (90) - (-48)
= (-31) + 6 = 90 + 48
= (-25) = 138
So both are not equal
=(1925 * 101) - 1925
= 194425 - 1925
= 192500
2) 37*{8+(-3)} = 378 + 37 (-3)
= 37* (8-3) = 378 + (-111)
= 37* (5) = 378 -111
= 185 = 267
So both are not equal
3) (-82) {(-4) + 19} = (-82) (-4) + (-82)*10
= (-82){15} = (328) + (-820)
(-1230) = (-492)
So both are not equal
4) {7-(-7)}*7 = 7*7-(-7) *7
=(14)*7= 7*{7-(-7)}*7
=98 = {7*(14)}*7
= 98 = (98)*7
= 98 = 686
So both are not equal
5) {(-15)-8}-6= (-15)*(-6)-8*(-6)
= {(-23) -8} -6 = {(-15)*(-6)} - {8*(-6)}
=(-31) - (-6) = (90) - (-48)
= (-31) + 6 = 90 + 48
= (-25) = 138
So both are not equal
