Q.


1.) 999 - 21 × 3 + 12 = ...

2.) 4³ - 2² = ...​

[tex] \sf999 - 21 \times 3 + 12[/tex]

[tex] \sf = 999 - (21 \times 3) + 12[/tex]

[tex] \sf = 999 - 63 + 12[/tex]

[tex] \sf = 936 + 12[/tex]

[tex] \sf = 948 \\ \\ [/tex]

[tex] \sf {4}^{3} - {2}^{2} [/tex]

[tex] \sf = (4 \times4 \times 4) - {2}^{2} [/tex]

[tex] \sf = (16 \times 4) - {2}^{2} [/tex]

[tex] \sf = 64 - {2}^{2} [/tex]

[tex] \sf = 64 - (2 \times 2)[/tex]

[tex] \sf = 64 - 4[/tex]

[tex] \sf = 60[/tex]

1.) 999 - 21 × 3 + 12

= 999 - (21 × 3) + 12

= 999 - 63 + 12

= 936 + 12

= 948

2.) 4³ - 2²

= (4 × 4 × 4) - (2 × 2)

= 64 - 4

= 60
