Step-by-step explanation:
1) 5+4×2
Multiply 4 and 2 to get 8.
5+8
Add 5 and 8 to get 13.
13
2) 4×8=2−17+11
Multiply 4 and 8 to get 32.
32=2−17+11
Subtract 17 from 2 to get −15.
32=−15+11
Add −15 and 11 to get −4.
32=−4
Compare 32 and −4.
3) 48=2−4=
Subtract 4 from 2 to get −2.
48=−2
Compare 48 and −2.
4) 12−5−4×3=
Subtract 5 from 12 to get 7.
7−4×3
Multiply 4 and 3 to get 12.
7−12
Subtract 12 from 7 to get −5.
−5
5) 18×2+155−12=
Multiply 18 and 2 to get 36.
36+155−12
Add 36 and 155 to get 191.
191−12
Subtract 12 from 191 to get 179.
179
