Question

Tính :

a. 13 + 98 x 12 

b. 78 x 45 + 0

c. 65 x 0 + 45 + 87 - 23

d. 99 + 1 x 100

 

 

Answer 1

a) 13 + 98 x 12 = 13 + 1176 = 4489

b) 78 x 45 + 0 = 3510 + 0 = 3510

c) 65 x 0 + 45 + 87 - 23

= 0 + 45 + 87 - 23

= 132  - 23 = 109

d) 99 + 1 x 100 

= 99 + 100 = 199

Answer 2

Tính : 

a. 13 + 98 × 12 

= 13 + 1176 

= 1189

b. 78 × 45 + 0 

= 78 × 45 

= 3510 

c. 65 × 0 + 45 + 87 - 23 

= 0 + 45 + 87 - 23 

= 45 + 87 - 23 

= 132 - 23 

= 109

d. 99 + 1 × 100 

= 99 + 100 

= 199

Answer 5

a) \(13+98\cdot12\)

\(=13+1176\)

\(=1189\)

b) \(78\cdot45+0\)

\(=3510+0=3510\)

c) \(65\cdot0+45+87-23\)

\(=0+45+\left(87-23\right)\)

\(=45+64\)

\(=109\)

d) \(99+1\cdot100\)

\(=99+100=199\)

Answer 7

a) 13 + 98 · 12
= 13 + 1176
= 1189
b) 78 · 45 + 0
= 3510 + 0 = 3510
c) 65 · 0 + 45 + 87 − 23
= 0 + 45 + 87 − 23
= 45 + 64
= 109
d) 99 + 1 · 100
= 99 + 100 = 199
