76x(1/23-1/53)+23x(1/23+1/76)-53x(1/23-1/76)

76x(1/23-1/53)+23x(1/23+1/76)-53x(1/23-1/76)

In the middle of the title, 1 / 23 in brackets should be 1 / 53, otherwise it is not easy
76x(1/23-1/53)+23x(1/53+1/76)-53x(1/23-1/76)=76x1/23-76x1/53+23x1/53+23x1/76-53x1/23+53x1/76=76/23-76/53+23/53+23/76-53/23+53/76=(76/23-53/23)-(76/53-23/53)+(23/76+53/76)=1-1+1=1

76×(1/23-1/53)+23X(1/53+1/76)-53X(1/23-1/76)
23 and 53 are followed by X, not multiplication

It's one!

Calculation: 76 × (123 − 153) + 23 × (153 + 176) − 53 × (123 − 176)=______ ．

76 × (123 − 153) + 23 × (153 + 176) − 53 × (123 − 176) = 76 × 123-76 × 153 + 23 × 153 + 23 × 176-53 × 123 + 53 × 176 = 76 × 123-53 × 123-76 × 153 + 23 × 153 + 23 × 176 + 53 × 176 ∧ 1-1 + 1 = 1

A simple algorithm of 76 * (1 / 23-1 / 53) + 23 * (1 / 53 + 1 / 76) + 53 * (1 / 23-1 / 76)
Please explain why,

76*（1/23-1/53）+23*（1/53+1/76）-53*（1/23-1/76）
=76/23-76/53+23/53+23/76-53/23+53/76
=(76/23-53/23)-(76/53-23/53)+(23/76+53/76)
=1-1+1
=1
