7+(15+1)x2+9-(7x0+16)+25-4x2+5+7=???
A=7+16x2+9-16+25-8+5+7
A=7+32-7+17+12
A=39-7+29
A=68-7
A=61
A = 7+( 15+1) *2+9-( 7*0+16) +25 - 4*2 + 5+7
= 7+ 16 * 2 + 9 - 16 +25 - 8 + 5+7
= 7+ 32 + 9 -16 + 25 - 8 + 12
= 39 + 9 -16 + 25 -8 +12
= 48 -16 + 25 -8 +12
= 32 + 25 - 8 + 12
= 57 - 8 + 12
= 49 + 12
= 61
