$- 55.4$ $-55.4$

Use the definition of the exponents:

$25.6 + 4 \cdot 4 \cdot 4 - 100^{0} - 12 \cdot 12$ $25.6+4*4*4-100^0-12*12$

Any number to the zeroth power is 1:

$25.6 + 4 \cdot 4 \cdot 4 - 1 - 12 \cdot 12$ $25.6+4*4*4-1-12*12$

Simplify:

$25.6 + 64 - 1 - 144$ $25.6+64-1-144$

$89.6 - 1 - 144$ $89.6-1-144$

$88.6 - 144 = - 55.4$ $88.6-144=-55.4$
